Brief introduction
SA-30 field analyzer is the development of the atomic spectrum analysis system (2011YQ140149), which is used in the field, the rapid and accurate determination of the atomic spectral analysis system (2012IK147). Apparatus and its application method for the development of the whole process of heavy metal speciation. Published in foreign SCI paper 1, the United States, China's invention patents 1.
SA-30 field analyzer will be used for the separation of heavy metal forms, which can achieve high efficiency separation under very low column pressure, also known as "low pressure high performance liquid chromatography", combined with the small low pressure liquid pump and "high efficiency light ultraviolet treatment" technology. Can realize the scene of different morphological elements to quickly separate and detect, and the sample and temperature control of the mixed spin extraction system, covering the whole process of heavy metal speciation analysis and detection.
Features
1. Established with monolithic column is the core of low pressure separation system, the same chromatographic column can form three elements as, Se, Hg, separation; can realize the arsenic and selenium speciation and determination to improve the analysis efficiency; due to the lower column pressure, velocity gradient elution and substantially reduce the analysis time, improve the analysis speed, improved peak shape is also very good.
2 in the light of UV processor, the efficiency is very high, without the need of auxiliary oxidant, anti organic solution and matrix interference ability. The volume of the interface device is significantly reduced, and the integrated low pressure chromatography infusion pump is still more than 50%, which is more suitable for the use in the field than the current SAP-20 has been commercialized.
The matching of the mixed spin extraction device can realize the automatic extraction and purification of the 8 samples in the 30min.
