LC-AF7590 liquid chromatography-atomic fluorescence spectrometer Introduction
At present, the trend in analytical chemistry is to identify and quantify actual chemical forms, not just the determination of total elements. Different forms of the same element have completely different chemical and toxicological properties. LC-AF 7590 Liquid Chromatography-Atomic Fluorescence Spectrometer (Atomic Fluorescence Photometer) came into being, modular design, atomic fluorescence host and liquid chromatography unit are separated for use, not only for elemental morphology analysis, but also for The total amount of elements is determined.
Application field
Food hygiene inspection, environmental sample inspection, geological metallurgical sample inspection, water sample inspection, agriculture and product inspection, clinical inspection, education and scientific research. Features
1.Species analysis of arsenic, mercury, selenium, antimony and other elements in the sample.
2.Modular design, the atomic fluorescence host can be separated from the liquid chromatography unit.
3.Specially designed UV digestion device, online digestion of organic matter, no UV light leakage, protect the human body from damage.
4.Strictly calculate the designed morphological analysis flow path. The post-column volume is small, reducing peak broadening.
5.With cleaning function, the waste liquid is directly discharged into the waste bottle when cleaning the chromatographic column, without entering the gas-water separator.
6.Parallel dual-piston reciprocating pump, microprocessor controlled fixed stroke, adjustable speed; structurally chemically inert, non-metallic PEEK material pump head and flow path pH 0-14; control mode fully controlled by software or front panel; maximum operating pressure 35 MPa (5000 psi); plunger cleaning Double plunger continuous automatic cleaning; overpressure protection upper limit 0-35 MPa, in increments of one unit, the lower limit can be set to a unit lower than the upper limit, the pump will be automatically stopped if the upper limit is exceeded ; Low pulsation infusion pump, wide flow rate range, stable operation, low maintenance cost.
7.Full PEEK flow path system to avoid metal pollution, high pressure resistance, strong acid, strong alkali and compatible organic solvents.
After liquid chromatography injection injection, the six-way valve is triggered, the workstation automatically collects data, the spectrum record is complete, and the peak time is consistent. Equipped with special liquid chromatography-atomic fluorescence detection software, it can realize continuous detection and collect data in real time, without the need for multiple software window operations.
8.Gradient leaching can be performed to shorten analysis time, improve resolution, improve peak shape, and shorten peak out time.
9.Using network port communication, fast speed and strong stability.
10.Autosampler (optional accessory)
11.Powerful and easy-to-operate software design
