Features

1High cost-effctive flame AAS

Reasonable design, adopting the same key parts as in high end instruments, ensures basic functions but less automation to provide an economic model for users

2 Reliable integration of main unit with microprocessor

Built-in microprocessor with necessary auto-control and data processing functions achieve high reliability of the instrument

3 Simple and easy operation

Eye-catching digital display, multi-function data processing ability and fast function-key direct input realize easy and fast analysis

Beijing Rayleigh Analytical Instrument Corporation (BRAIC) is a leading manufacturer of spectroscopic instruments in China. Since it was founded in 1968, the company has been devoting itself to the research, development and manufacture of spectroscopic instruments with thirty years experience in this field, BRAIC now offers six series of over 20 models of products, which include atomic absorption spectrophotometers, optical emission spectrometers, UV/VIS spectrophotometers, FTIR spectrometers, biochemical analyzers and grating monochromators. The instruments serve a wide range of industries such as pharmaceuticals, foods, chemical, petroleum, agriculture, metallurgy, geology, environmental protection etc..

The company incorporates a machining workshop, an optical processing workshop and a grating laboratory, which are all equipped with high precision equipment and advanced technology for instrument manufacturing. It is also provided with several test rooms necessary for instrument quality examination. To provide good after-sales service, we have a strong service team in the factory and a service network all over China. BRAIC is also among the first in analytical instruments field to have passed the ISO9001 certification of international quality system.

For the past decades, BRAIC has successfully imported the advanced technologies from countries of France, Japan, Switzerland and the United States for the manufacture of atomic absorption spectrophotometer, UV/VIS spectrophotometer and FTIR spectrophotometer, etc. The instrument manufacturing technology has reached the world level. BRAIC's products are not only sold well in domestic market, especially the atomic absorption spectrophotometers which occupy nearly 50% of the domestic market shares, but also exported to foreign countries of USA, Korea, Southeast Asia, Europe and Africa etc.

BRAIC, the pride of Chinese analytical instruments manufacturer.
