ATR fully automatic parallel concentratorIt is an automated equipment based on vortex airflow method, water bath heating, and nitrogen oblique blowing technology, which achieves efficient and precise concentration of multi-channel samples through independent vacuum pipelines, optical sensing probes, and intelligent control systems. Its core applications cover the following areas:
1. Detection of agricultural residues and environmental pollutants
Application scenarios: Concentrate pesticide residues (such as organophosphates and pyrethroids) in complex matrix extracts of vegetables, fruits, grains, and trace pollutants (such as heavy metals and polycyclic aromatic hydrocarbons) in soil, sediment, and water bodies.
Technical advantages:
High throughput processing: Supports synchronous concentration of 8-16 samples, reducing single batch processing time to 1/4 of traditional methods (for example, reducing the concentration time of 200 vegetable samples from 8 hours to 2 hours).
Anti cross contamination: Independent vacuum pipeline and sealing design to avoid crosstalk between samples and ensure data accuracy.
Precise endpoint control: Through optical probes or volumetric sensors, it automatically stops when concentrated to a preset volume (such as 0.5mL or 1mL) to prevent loss of the target substance, meeting national standards such as GB 23200.113-2018.
2. Biopharmaceuticals and Pharmaceutical Analysis
Application scenarios: Concentrate drug metabolites, hormones or proteins in biological fluids such as serum, plasma, urine, as well as active ingredients in traditional Chinese medicine extracts.
Technical advantages:
Low temperature protection: The heating temperature of the water bath can be adjusted to 30-40 ℃ to prevent the degradation of heat sensitive components (such as vitamin C and antioxidants), reducing the sample loss rate from 12% to 3%.
Gradient negative pressure control: In the initial stage, high vacuum is used to rapidly evaporate the solvent, and in the later stage, the pressure is reduced to prevent boiling and ensure the complete retention of the target substance.
High recovery rate: The solvent recovery rate remains stable at over 90%, reducing the harm of toxic solvent volatilization to operators.
3. Analysis of Food, Beverage, and Nutritional Components
Application scenarios: Concentrate protein, fat, vitamins, amino acids and other nutrients in samples such as milk, juice, and alcohol, as well as preservatives, plasticizers, pigments and other additives.
Technical advantages:
Low temperature concentration: Operate in a vacuum environment of 30-40 ℃ to avoid the decomposition of heat sensitive components caused by high temperatures. For example, concentrate 100mL of fruit juice to 0.5mL to meet the quantitative detection limit requirements of the national standard for vitamin C.
Solvent recovery: The condensation system can recover solvents such as ethanol, reducing detection costs.
Research on flavor compounds: Concentrate volatile components (such as esters and alcohols) in beer and wine to assist in flavor characteristic analysis or quality evaluation.
4. Third party testing and inspection field
Application scenario: Processing large-scale samples (such as water quality monitoring, agricultural product testing, ocean sample analysis), supporting synchronous concentration of 12-48 samples, and improving detection efficiency.
Technical advantages:
Intelligent operation: equipped with a touch screen and preset parameter library, supporting gradient adjustment of parameters such as temperature, vacuum degree, and speed to adapt to different solvent characteristics.
Real time monitoring and reminders: Concentrate endpoints through SMS or software notifications to achieve unmanned operation.
Compliance assurance: Complies with international standards such as ISO 9696:2007 and EJ/T 1075-1998, meeting the pre-treatment requirements for radioactive water samples, pesticide residues, and other testing.
5. Research and process optimization
Application scenario: Concentrate plant extracts (such as tea polyphenols, caffeine) or target active ingredients in fermentation broth, and evaluate the efficiency of extraction and purification processes.
Technical advantages:
Circular shaking function: promotes solvent evaporation and shortens concentration time (more than 50% faster than traditional methods).
Dilute to dry powder: Supports concentrating the sample to a dry powder state for subsequent analysis by high-performance liquid chromatography (HPLC) or mass spectrometry (MS).
Data traceability: Record operation logs and parameter curves to provide data support for process optimization.
