Introduction

Paramagnetic oxygen analyzer only partial pressure sensors, rather than the volume concentration of the reaction, is widely used in industry, laboratories and other areas. in Reference under pressure analyzer rated measuring range of 0% to 1% and 0% to 100%. Only a few gas paramagnetic (for example. oxygen, nitric oxide and nitrogen dioxide). Oxygen has a strong paramagnetic susceptibility (see Appendix A), based on the characteristics of oxygen in most industrial applications, it can be designed to have a high specificity of the analyzer, such as measurement of high hydrocarbon background The oxygen content of the compound. About paramagnetic oxygen measurement technology has many different descriptions, but commercially available analyzer mainly in the following three ways. --- Automatic zero balance (magnetic mechanical); --- Thermal-magnetic or magnetic wind; --- Pressure (or Quincke) method. These methods require the sample gas cleaning and drying by heating and other improvements, so easily condensed at low temperatures of the sample gas can be analysis. For these reasons, before the sample gas measurement response appropriately. Performance of gas analyzers Part 3. paramagnetic oxygen analyzer

1 Scope

GB/T 18403 in this section applies to the three main methods, these three methods have been described in the introduction. This section relates to the basic assist Unit for indoor and outdoor installation analyzer. Note. The key security system requirements need to add that this part of the technical performance of the analyzer does not contain this part. The purpose of this section is. --- Specifies the terms and definitions paramagnetic gas analyzer features measurement of oxygen in the sample gas; --- Unified class analyzer features and verification methods; --- Specifies the test content and test methods for determination of functional characteristics should be carried out; --- Documents provide the basis for the ISO 9001 quality management standard applications.

3 Terms and Definitions

GB/T 18403.1-2001 and as defined in the following terms and definitions apply to this document. 3.1 Susceptibility magneticsusceptibility Measuring the amount of change of the magnetic field strength of the test substance and the vacuum magnetic field intensity, see equation (1). X = H1-H (1) Where. X --- susceptibility, dimensionless; The magnetic field strength H --- vacuum state in amperes per meter (A · m-1); H1 --- test substance in the magnetic field strength in amperes per meter (A · m-1). 3.1.1 Paramagnetic substance paramagnetism You can increase the magnetic field strength of the material (X > 0). 3.1.2 Anti (against) a magnetic substance diamagnetism You can attenuate the magnetic field strength of the material (by H1 \u003cH,所以X\u003c0)。
