The recent advance on valence state analysis of chromium by flow injection-atomic spectrometry;

This paper covered with the determination of arsenic by atomic spectrometry in the last few years,including atomic absorption spectrometry(AAS),atomic fluorescence spectrometry(AFS),inductively coupled plasma atomic emission spectrometry(.

Taking petroleum sodium sulfonate as sodium organometallic compound,the lower freezing point base oil as the prepared oil,the organo-sodium standard substance used for atomic spectrum was developed and calibrated with the one made by America CONSTANT Corporation.

The development of organo-copper standard substance used in atomic spectrum is introduced.

At the same time,it deeply discusses the effects on transition in atomic spectrum from spectrum fine structure,transition probabili- ty,spectrum outline and spectrum intensity in order understand the problem of transition of atomic spectrum to better.

The principle, classification and characteristics of charge transfer device detectors are introduced, and their applications in anaytical chemistry, such as molecular spec-troscopy, atomic spectroscopy, Raman spectroscopy, separation and image analysis, have been reviewed with 74 references.

The high temperature measurement method based on the theory of atomic spectroscopy, that is multi-spectrum average method and multi-spectrum slope method, has great significance.
