3 Overview

Oil in water by infrared spectrophotometry concentration analyzer (hereinafter referred to as the oil content analyzer) is based on the molecules of the substance in the infrared region Characteristic absorption spectra and Lambert - Beer law, the extracted oil in water measurement points after the instrument. Water and oil through tetrachloride Carbon extraction in the wave number of 2930cm-1 (CH2 groups CH bond stretching vibration), 2960cm-1 (CH3 Stretching group CH bond) and 3030cm-1 (aromatic CH bond stretching vibration) all or a portion Sub-band at a characteristic absorption, extraction agent carbon tetrachloride in the feature area no absorption peaks characteristic absorption material mainly stone Oils and animal and vegetable oils, and its content from the absorbance at the characteristic bands are calculated. Oil content analyzer, infrared spectrophotometry into oil content analyzer (hereinafter referred to as Class A equipment) and non-dispersive infrared spectrophotometry Oil Analyzer (hereinafter referred to as Class B instruments) categories. A class instrument, you can wave number scanning, quantitative measurement of oil in multiple infrared absorption characteristics, such as the wave number 2930cm-1,2960cm-1 and characteristic peaks at 3030cm-1 is. Such equipment by using the experimental method is divided into Room, portable and on-line three kinds. Class B instruments, fixed wave number, usually only the feature 2930cm-1 absorption at 3.4μm or measured. Technical information and test equipment to be submitted by the applicant 4 4.1 Technical Information 4.1.1 prototype photos. 4.1.2 product standards (including test methods). 4.1.3 assembly diagram, schematic diagram and major components. 4.1.4 User's Guide. Test report 4.1.5 manufacturing units or technical bodies do. 4.2 Test Instrument The applicant should provide their own production equipment.
