Test method for particles in electronic grade water by instrument1 ScopeThis Part of GB/T 11446 specifies the instrumental method for the determination of particles, in electronic grade water. This Part applies to the continuous or single detection and counting of particles, in electronic grade water. The measured particle size is not less than 0.05 μm; the concentration range of the particles is 0 ~ 10000 pcs/mL.2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) is applicable to this standard. GB/T 11446.1-2013 Electronic grade water3 Terms and definitionsThe terms and definitions as defined in GB/T 11446.3-2013, as well as the following terms and definitions, apply to this document. 3.1 Particle Granular, gas removed, non-liquid substance, which is non-uniformly dispersed in water.4 Principles of the methodA focused laser beam is incident perpendicular to the direction of the water sample flow. The particles in the water will produce a light scattering effect. The intensity of the scattered light has a certain relationship, with the size of the particles. The scattered light focuses on the photomultiplier, through the collecting lens, at which the light signal is converted into electrical pulse.5 Disturbing factors5.1 The factors, such as sampling process; pollution of the container, environment and detection chamber; bubbles in the water and vibration of the measurement process; changes in water flow speed, etc., 5.2 The ambient temperature affects the stability of the analysis results. The temperature of the laboratory and the environment shall be between 10 °C and 30 °C. 5.3 Whether the instrument is normal or not, directly affects the measurement result. Therefore, it shall be calibrated, in accordance with the calibration cycle, which is specified in China, when it is used.6 Reagents6.1 Blank water. EW-I electronic grade water, which is specified in GB/T Microcomputer7 Measuring instrumentsA laser-scattering type submicron liquid particle counting and detecting instrument, which has a microcomputer.8 Operation procedures8.1 Preparation before instrument test Turn on the power, according to the instrument's instructions, to make the instrument enter the ready-to-work state. 8.2 Test method 8.2.1 Continuous sampling First use the degreasing detergent, to clean the pipe. Then lead in EW-I electronic grade water, to rinse it for 30 minutes. Perform the test, according to the operating rules of the continuous test of the instrument.9 Calculation of measurement resultsCalculate the particle number concentration, according to formula (1).10 Error analysisThe relative deviation of this method is less than 20%.11 ReportThe test report shall be prepared, according to the format, which is given in GB/T 11446.3-2013. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
