Fusion type micro sample bottle is a sample container commonly used in analytical instruments such as gas chromatographs, liquid chromatographs, mass spectrometers, etc. It is particularly suitable for the storage, transportation, and analysis of micro samples. It usually has good sealing and stability, ensuring that the sample is not contaminated or altered by external factors during the analysis process.
purpose
Sample storage:
Used for storing trace amounts of liquid, gas, or solid samples, it can effectively prevent sample volatilization, oxidation, contamination, etc.
Commonly used for storing small amounts of samples that require long-term preservation, especially for photosensitive, volatile, or environmentally sensitive substances.
Sample analysis:
Among various analytical instruments, fusion type micro sample bottles are used to introduce micro samples into the instrument for analysis. Its sealing and precision design can ensure the stability of the sample during the analysis process, avoiding sample loss.
In analysis such as gas chromatography and liquid chromatography, accurate sample injection can be provided.
Sample transportation:
Used for the transportation or transfer of samples, especially trace liquids or volatile chemicals. Due to its sealing design, it can prevent sample leakage and deterioration, ensuring stability during sample transportation.
Handling of small samples in experiments:
Suitable for handling trace samples to avoid affecting sample quality or loss due to excessive container volume.
Precautions
Choose the appropriate bottle size:
Select a suitable volume of micro sample bottle based on the sample size. The usual capacity is 0.5ml, 1ml, 2ml, etc. It is important to avoid large bottles that create too much air space for the sample, which can affect the accuracy of the analysis.
Sealing inspection:
Ensure good sealing of the bottle cap and body to avoid sample evaporation or contamination caused by poor sealing.
Check if the bottle cap is intact, ensuring no damage or deformation, and if the sealing gasket is in place.
Cleaning and Removing Pollution:
Before use, the sample bottle must be cleaned to avoid any residual substances inside the bottle affecting the sample.
Use appropriate cleaning agents during cleaning to ensure the removal of oil stains, chemicals, etc., and prevent cross contamination.
Sample loading:
When loading samples, avoid overfilling. The maximum capacity of the bottle should not be exceeded, and it is usually recommended to leave a small amount of space to prevent sample leakage during heating or pressure changes.
During the bottling process, avoid direct contact of the sample with the bottle mouth and maintain cleanliness inside the bottle.
Prevent sample loss during use:
Avoid inverting, colliding, or violently shaking the bottle during operation to prevent sample spillage or loss.
If there is a gas sample in the bottle, ensure that the pressure difference between the inside and outside of the bottle is appropriate to prevent gas leakage.
Storage conditions:
Select a suitable storage environment based on the characteristics of the sample. Some samples may need to be refrigerated or stored away from light to avoid sample decomposition or deterioration.
For volatile samples, high temperatures or direct sunlight should be avoided to prevent sample evaporation and loss.
Avoid sudden temperature changes:
Avoid drastic temperature fluctuations during use, and prevent pressure changes or sample deterioration caused by temperature differences inside the bottle. When necessary, the sample bottle can be preheated or pre cooled to a suitable temperature.
Attention during injection:
When using fusion type micro sample bottles for gas chromatography or liquid chromatography analysis, ensure that the connection between the syringe and the bottle mouth is stable to avoid sample leakage.
Before conducting analysis, it should be ensured that the sample bottle is stable and free of bubbles to ensure accurate analysis results.
Regular inspection:
Regularly check the usage status of sample bottles, especially the aging of bottle caps and sealing gaskets. If wear or damage is found, it should be replaced promptly.
Through these precautions, the fusion type micro sample bottle can be efficiently and safely used for sample storage, transportation, and analysis, ensuring the quality and stability of the sample throughout the entire experimental process.
