Atomic absorption spectrophotometer (hydride)-Flame integrated)

1、 Introduction

4520QIt is a multifunctional atomic absorption spectrometer specifically designed for industries such as food and feed. The built-in design of the hydride generator saves more space and provides better stability. Can be equipped with a graphite furnace system and expanded for combined use.

• application field

Widely used in industries such as food, feed, geology, metallurgy, medicine, chemical engineering, petroleum, agriculture, environmental protection, and commercial inspection.

• matching products

Hollow cathode lamp, hydride generator, microwave digestion instrument, ultrapure water machine, oil-free silent air compressor.

• Performance characteristics

Embedded hydride atomizer system

The integrated flame atomizer and hydride atomizer are easy to operate and can detect low-temperature elements such as mercury, arsenic, selenium, etc.

One click sampling detection

High degree of automation, good stability, and minimal sample interference.

◆ Automatic switching of multiple light positions

Preheat multiple lamps simultaneously with multiple lamp positions to save waiting time. Deuterium lamps can be used to fasten the background and high-performance element lamps can be selected.

◆ Automatic optimization of instrument settings

The instrument automatically optimizes the memory function for setting conditions and completes peak scanning with one click.

◆ Data reports can be saved in multiple formats and printed out for easy data retrieval and comparison.

Software design makes operation simpler

The instrument software adopts a single interface multifunctional window design, making operation simpler, real-time monitoring of data changes, and supporting mainstreamWindowsOperating system, supports remote control and calibration/The English version is optional.

◆ * Reliable multiple security protection system

Automatic detection, alarm, abnormal situations such as insufficient pressure, air leakage, and engine shutdown;

◆ Scalable: Graphite furnace system and combined functions

◆ Equipped with automatic online detection function
