EXPEC 580 full-automatic QuEChERS processing workstation is an instrument designed to automatically
run QuEChERS pre-treatment method under unattended condition. The workstation has built-in national
standards and pharmacopoeia and other standard methods, and it can be operated just by one click to
automatically complete whole process of sample liquid adding, salt adding, oscillation, vortex,
centrifugation, separation, purification, etc., so as to realize the processing of batch samples, ensure the
accuracy and stability of test, and protect the health of experimental personnel. It can be applied to all
kinds of food safety testing, determination of pesticide residues in medicinal materials, tobacco and tea,
and other testing conducted with QuEChERS pretreatment method.
The system has built-in the QuEChERS methods and processes specified in the national standards GB 23200.113-2018 and GB 23200.121-2021, and can run automatically with one click to realize sample extraction and purification.
Ensure the accuracy of liquid treatment, and function for liquid level detection and strong cleaning at the same time, thus effectively preventing the pollution
Simulate manual oscillation to ensure stable and reliable sample extraction and purification effect
Realize ice bath of samples, meet the requirements of Chinese Pharmacopoeia (2020), and effectively prevent the loss of the target caused by the fever of the extracted salt
Realize that samples based on different substrates can be processed in the same batch by adding different extracted salts without changing the salt bin, which can effectively prevent the caking of extracted salt.
50mL/15mL centrifuge tubes can be placed at the same time
Low temperature control of the centrifugal chamber can effectively prevent the loss of target matter
Realize multi-channel high-speed sample mixing, and ensure sample purification effect
The system monitors various faults such as centrifuge weight mismatch fault, switch cover fault, sample tube transfer fault in real time, and feeds back the faults to the user interface in time
Determination of residues of pesticides and their metabolites in plant-derived food
Determination of pesticide residues in animal-derived foods
Determination of residues of multiple banned pesticides in medicinal materials and decoction pieces (plants)
Other testing and determination using QuEChERS method
