Introduction

Photometric analyzer using UV detector for different wavelengths of the electromagnetic spectrum (180nm ~ 20µm), the visible and infrared light response Detecting instrument. Within these wavelength ranges having a plurality of gas absorption/emission spectrum. Using these spectral analyzer designed to be Using a variety of techniques, including absorption and stimulated emission spectra, and the intensity of the radiation/response wavelength conversion. The volume of gas to be measured can Sample cell is controlled by the sample gas can be treated or not, can directly measure its concentration in the sample gas.

Performance of gas analyzers Part 6. Photometric Analyzer

1 Scope

GB/T 18403 in this section apply to the use of spectrophotometric techniques to measure various types of mixed gas of one or more components or vapor concentrations Type of analyzer. This portion of the GB/T 18403.1-2001 combination.

This section applies to the use of the analyzer and the use of the non-dispersive and dispersive wavelength selection absorption spectra, emission spectra or wavelength conversion technique Analyzer.

This section applies to all types of measuring gas sample analyzer, whether or not sample gas, sample gas or in a vacuum, atmospheric and pressurized Article Member under can.

This section applies to directly measure the gas concentration in the sample gas in all types of analyzer.

The purpose of this section is.

--- Provisions photometric technology utilizing continuous measurement air supply terms and definitions gas or vapor concentration in the gas analyzer functional properties;

--- Unified class analyzer features and verification methods;

--- Specifies the test content and test methods for determination of functional characteristics should be carried out;

--- Provide basic document for the ISO 9001, ISO 9002 and ISO 9003 quality management standard applications.
