1、 Core industry application scenarios and operational standards

（1） Pharmaceutical industry: Surface sampling of raw materials and intermediate products

1. Applicable scenariosSurface sampling of liquid raw materials (such as pharmaceuticals, solvents), powder excipients (such as fillers, stabilizers), and semi-solid intermediates (such as ointment matrices).

2. Tool SelectionPriority should be given to using 316L stainless steel material (resistant to chemical corrosion and easy to sterilize), and the handle length should be selected according to the depth of the material container -500mm handles are selected for small laboratory containers, and 1000-1500mm handles are selected for large workshop storage tanks; Select the spoon volume (50-1000ml) based on the sampling amount, such as 50ml for trace drug solutions and 250-500ml for bulk excipients.

3. operation steps

• Liquid raw materials: Slowly insert a long spoon into the surface of the container to avoid layering caused by stirring, steadily scoop out the sample, and directly transfer it into a sterile sampling bottle (125-250ml wide mouthed bottle, sterilized in advance).

• Powder auxiliary materials: After opening the material packaging, use a long spoon to randomly select 3-5 points on the surface of the stack, each scoop an equal amount of sample (5-10g per point), collect and mix on sterile kraft paper, and then transfer to a sampling bottle.

• Tool preprocessingRinse the long spoon with purified water three times before sampling, let it dry naturally, and then place it in a sterile cloth cover; If sterilization is required, use moist heat sterilization (121 ℃, 30 minutes) or dry heat sterilization (160 ℃, 2 hours), and cool for later use.

• Sampling operation：

• subsequent processingImmediately seal the material packaging after sampling, and affix a "sampling certificate" (indicating the product name, batch number, sampler, and date) on the outer layer of the packaging; Label the sampling bottle and fill in the sampling record (including the number of samples, quantity, and reviewer); The remaining samples will be kept for one month for future reference, and the samples will be retained for one week after the inspection report is issued.

4. PrecautionsIf the sampled material is toxic/corrosive (such as strong acid solution), acid and alkali resistant gloves and goggles should be worn to avoid direct contact; The entire sampling process is sterile to prevent microbial contamination.

（2） Food industry: safety sampling of raw materials and finished products

1. Applicable scenariosSurface sampling of liquid raw materials such as edible oil and syrup, powder raw materials such as flour and milk powder, and suspended/semi-solid finished products such as jam and sauce.

2. Tool SelectionSelect 304 stainless steel material (in compliance with food contact grade standards), adjust the length of the handle according to the height of the storage tank (such as 1500mm for workshop oil tanks and 500mm for laboratory small buckets), and match the detection requirements for spoon body volume (such as 50-100ml for microbiological testing and 250-500ml for component analysis).

3. operation steps

• Liquid raw materials (such as edible oil): Insert a long spoon along the wall of the container into the surface, slowly scoop it out (to avoid generating bubbles that affect the detection), and directly transfer it into a sterile sampling bottle. Select 3 different containers from each batch for sampling.

• Powder raw materials (such as flour): After opening the packaging bag, use a long spoon to take 1 spoon (about 20g per spoon) from the bag mouth, middle, and bottom, mix them, and put them into a sealed sampling bag, labeled with the "food grade" label.

• Semi solid finished product (if sauce): Use a long spoon to take a small amount of each of the upper, middle, and lower surfaces of the finished product can, mix them, and transfer them to a clean container to avoid the spoon body coming into contact with the pollutants at the can mouth.

• Tool preprocessingClean the long spoon with food grade detergent, rinse it three times with purified water, dry it, place it on a clean enamel plate, and cover it with sterile gauze; If microbiological testing is required for sampling finished products, the tools need to be sterilized with ultraviolet radiation for 30 minutes.

• Sampling operation：

• subsequent processingClean the tools after sampling (rinse with hot water and dry), and the sampling record should include "food batch number, testing items (such as microbial limits)"; The sample needs to be refrigerated at 4 ℃ and sent for testing within 24 hours.

4. PrecautionsBefore sampling, check whether the material packaging is intact. If packaging damage or material clumping is found, sampling should be suspended and reported; Avoid cross sampling with the same tool (such as taking acidic sauce first and then alkaline syrup) to prevent material reactions.

（3） Chemical industry: Sampling of chemical and raw material quality

1. Applicable scenariosSurface sampling of low viscosity liquid chemicals such as ethanol and solvents, powder raw materials such as fertilizers and pigments, suspensions/high viscosity materials such as coatings and adhesives.

2. Tool SelectionCorrosive materials (such as hydrochloric acid and caustic soda solution) are made of 316L stainless steel, while ordinary chemicals are made of 304 stainless steel; The handle length is adapted to the height of the chemical storage tank (e.g. 1500mm for large reaction vessels), and the spoon volume is adjusted according to the detection accuracy (e.g. 100-250ml for purity detection and 500ml for concentration detection).

3. operation steps

• Low viscosity liquids (such as solvents): Use a long spoon to quickly scoop up surface samples (to avoid volatilization), immediately transfer them to a sealed sampling bottle (with a PTFE stopper), and label it with a "corrosive/flammable/explosive" warning.

• Powder raw materials (such as fertilizers): Use a long spoon to take samples at different points in the material pile (about 50g per point), mix them, and put them into leak proof sampling bags to avoid powder flying (dust masks can be worn).

• High viscosity materials (such as coatings): Dip a long spoon into the surface material, scrape it into the sampling container, and clean the spoon body with a solvent (such as acetone) after sampling to prevent material clumping.

• Tool preprocessingClean the long spoon with industrial detergent, rinse it three times with deionized water, air dry and place it in the anti-corrosion toolbox; If the sampled material is flammable and explosive (such as ethanol), the tool needs to remove static electricity (connected with a grounding wire).

• Sampling operation：

• subsequent processingAfter sampling, close the valve of the material storage tank and clean the site (if there is any material leakage, it needs to be treated with neutralizing agent); Sampling records should indicate the "hazard level" of the material, and the samples should be stored according to chemical storage requirements (such as avoiding light and ventilation).

4. PrecautionsProtective equipment (acid and alkali resistant clothing, gas masks, anti-static shoes) must be worn during sampling; If the material is toxic, it should be operated in a fume hood to avoid inhaling volatile gases.

（4） Environmental Protection Industry: Surface Sampling of Water Bodies and Sewage

1. Applicable scenariosNatural water bodies such as rivers and reservoirs, as well as surface sampling of wastewater from chemical plants and sewage treatment plants.

2. Tool SelectionSelect 304 stainless steel material (resistant to water corrosion), adjust the length of the handle according to the sampling depth (such as selecting 500-1000mm for shallow water areas and 1500mm for deep water areas), and the spoon body volume is 250-500ml (meeting the requirements for single detection).

3. operation steps

• Natural water body: Insert a long spoon into the water surface 5-10cm below (surface layer) at a distance of 1m from the shore, scoop it steadily, and transfer it into a brown sampling bottle (to avoid light affecting water quality). Take 3 parallel samples at each sampling point.

• Sewage: Take a sample 0.5m downstream of the sewage discharge outlet, quickly scoop it with a long spoon (to avoid sediment mixing), transfer it to a corrosion-resistant sampling bottle, and label it as "sewage type (such as industrial sewage/domestic sewage)".

• Tool preprocessingRinse the long spoon with deionized water three times, air dry and place it in a clean sampling box to avoid contact with pollutants; If the sampled wastewater contains heavy metals, the tool needs to be soaked in nitric acid for 10 minutes in advance (to remove surface impurities).

• Sampling operation：

• subsequent processingAfter sampling, clean the tool with deionized water and dry it for later use; The sampling record should include "sampling point location, water temperature, pH value", and the sample should be sent to the laboratory for analysis within 24 hours.

4. PrecautionsIf there is an odor or unknown pollutant in the sampled water, a gas mask should be worn; Avoid sampling during rainy days or water disturbances to prevent sample distortion.

2、 General operating principles and tool maintenance

（1） General Operating Principles

1. Principle of representativenessSampling should cover different parts of the material (such as the upper, middle, and lower parts of the container, and different points in the material pile) to avoid deviation in results caused by single point sampling.

2. Hygiene/Safety PrinciplesTools that come into contact with food and medicine must be sterile/food grade, tools that come into contact with chemicals must be corrosion-resistant and anti-static, and corresponding protective equipment must be worn throughout the process.

3. Record traceability principleAll sampling processes must be fully recorded (including material information, tool information, and operator), with sample labels consistent with packaging labels for easy traceability.

（2） Tool maintenance and upkeep

1. cleanAfter each use, clean according to the type of material - ordinary materials should be cleaned with water and detergent, corrosive materials should be treated with neutralizing agents (such as alkaline solution) before rinsing, and sterile materials should be washed with purified water and sterilized.

2. storageAfter cleaning, the long spoon needs to be air dried/dried to avoid moisture and rust; 304/316L stainless steel tools should be kept away from strong acid/alkali environments and can be placed in a dry and sealed toolbox to avoid deformation of the spoon due to collision.

3. checkRegularly check if the welding between the spoon body and handle is secure (to avoid detachment during sampling), and if there are scratches or rust on the surface (if necessary, replace to prevent material residue).

3、 Model Selection Reference Table

By following the above industry-specific operation guidelines, it is possible to ensure the standardized application of stainless steel long spoon samplers in different scenarios, meeting industry standard requirements while ensuring the accuracy and reliability of sampling results.
