1 Scope

GB/T 5275 provisions of this part of the component calibration gas mixture generated by electrochemical method and introduced into the carrier gas flow calibration preparation Methods. Changed by changing the gas flow rate through the electrolytic cell or to change the composition of the charge gas mixture. Calibration gas mixture content Relative expanded uncertainty U by the relative combined standard uncertainty multiplied by a coverage factor k = 2 obtained, its value is not more than 5%. The preparation method for the preparation of multi-part predetermined volume fraction in the range of 0.1 × 10-6 ~ 250 × 10-6 calibration mixed gas. Note 1. The gas generating electrochemical method available include oxygen (O2), hydrogen (H2), hydrogen cyanide (HCN), hydrogen sulfide (H2S), chlorine (Cl2), bromine (Br2), dioxane Chloride (ClO2), ammonia (NH3), nitric oxide (NO), nitrogen (N2), carbon dioxide (CO2), phosphine (PH3), arsine (AsH3) and ozone (O3). Note 2. The advantage of electrochemical law capable of producing stable calibration gas mixture quickly within a few minutes. Note 3. The gas mixing system with an electrochemical gas generating device and a thermal mass flow controller, is equipped with computers and automatic control device, can be Commercial development. Examples See Appendix A.

3 Steps

3.1 Principle The electrochemical method is the basic method of the occurrence of gas produced, the occurrence of electrochemical method, the calibration component is generated by an amount proportional to the amount of the charge, Faraday constant scale factor [1mol electrons (or single-charged ions) the amount of charge transferred] reciprocal equals Avogadro's number (NA) And the charge of an electron (-e) of the product. F = NA × e (1) Where. F --- 96485.3415C/mol, the relative uncertainty of 4.0 × 10-8 (see reference [1], [2] and [3]). Chapter 5 given as long as conditions are met, the exact determination of the amount of gas current can be determined by cell produced. ......
