自动化 QuEChERS 系统
Automatic QuEChERS System
Though QuEChERS pesticide residue preparation method is widely employed, it is labor-intensive, inefficient, error-prone, and poorly reproducible when the sample quantity is large. Fully automatic QuEChERS system integrates multiple functions including automated liquid /salt /ceramic homogenizer feeding, oscillating, vortexing, centrifuging, ice bath, and precision pipetting. It can handle 32, 40, or 60 samples in a single test. With simple operation and no personnel involvement, it can avoid manual errors, ensure accuracy and stability of detection, realize fully automated detection, and improve test efficiency.

Dioxin Preparation & Cleanup
FMS introduces a new family of integrated, economical sample cleanup systems that combine manual sample prep steps into one automated process. EconoPrep® systems perform sample cleanup, fractionation and concentration for up to eight samples simultaneously in less than 1 hour, while delivering the highest recoveries and best results for all target Dioxin and PCB analytes. The systems are programmed and controlled via an easy-to-use touch screen and methods are stored on SD cards. A flexible system that allows running a single sample preparation step, such as sample cleanup, fractionation or concentration is also an option.

Molecular Distillator / Thin film Evaporator
Molecular distillation, also known as short-path distillation, is a continuous distillation process carried out under high vacuum (vacuum degree <10Pa). The mean free path of vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so the liquid mixture can be separated by utilizing the difference in evaporation rates of the components in the liquid.

Magnetron Sputtering Device for SEM
In order for samples to be imaged in an electron microscope, they need to be conductive, which is accomplished by coating the sample with a conductive layer to suppress charge, reduce thermal damage, and increase the secondary electron signal required for localized inspection in the SEM.

SFD (Supercritical Fluid Drying) Systems
In traditional drying methods, liquid is directly converted into gas under high temperature conditions, which will generate a certain amount of surface tension and destroy the fine structure of the sample. For special samples, such as sol-gel, biological samples, and porous materials with unstable structures, the use of traditional drying methods to pre-treat the samples will cause the sample structure to be damaged. However, using the critical point drying method, the medium uses a phase change method of liquid carbon dioxide-supercritical carbon dioxide-gas carbon dioxide, which will reduce the surface stress of the interface to zero, so the fine structure of the sample can be preserved...

SFE (Supercritical Fluid Extraction & Fractionation)
Supercritical fluid extraction (SFE, short for supercritical extraction) is a technique that uses supercritical fluid as an extractant to separate a component (extract) from a mixture (matrix). Carbon dioxide (CO2) is the most commonly used supercritical fluid. Extraction kettle: volume 100-3000ml, made of 316 stainless steel, equipped with electric heating system, adjustable temperature, special barrel, maximum working pressure 50MPa, can be equipped with more extraction kettles. Separation kettle: volume 50-500ml, made of 316 stainless steel, equipped with electric heating system, temperature adjustable. Maximum working pressure 20MPa, can be equipped with more separation kettles.
