Infrared Spectrometer FTIR1730 Trouble
Open instrument switch, Chau test instrument performance, low power computer screen (normal energy should be around 3000), determination of the instrument does not work, and produce measurement error is zero energy equipment can not work. (1) nan long-term source of energy is too low to make jq ① aging deterioration, then replace the Sunbeam 【! 『J O to make the energy behind the normal host special desiccant ② timely regeneration of failure will also affect energy use. Dried at 240 ℃ 24 hours under the conditions of regeneration, enable the energy increased. @ Park, humid air between the KBr windows of the sample affect the light intensity of deterioration will reduce the energy. Remove the O of the K windows grinding. Make transparent, the energy can be increased. ④ cases than the entire test sample Xuan. _j 』Energy can also return to normal. (2) most of the energy mold of such failure is due to a bad electronic circuit components. ① Laser amplifier voltage change in the normal position should be between 8 ~ 16V. Adjust the amplifier, Ⅲ oscilloscope measurements, until the voltage is back to normal. ② AnaloguePCB line l occurred as shown in the circuit therefore pick up line search method is as follows: ① observed opening the cover if the laser light source and light proof if part of the normal two. Then observe whether the light path I! j] were offset. If offset should be adjusted. ② to check with the display transition IstrumentContral (r switch to page 44) of the instruments 44 3 1993 rl. Third, with the crossing power () ah 5 wave power on the water response Hui Xi hatch ring cut number of working gas flow of gas and water 1.0 × 10 50mL/mi ~ a 'g sensitivity is 1.5 × 10 a g / s . The linear range was 5 × 10 for a 6 × lOg,[link widoczny dla zalogowanych], when the water content of 5x10 ~ 5 × lO a 0g range, the linear regression equation was Y = 363.2x ~ 0.1726, a 0.9999 correlation coefficient R . Concentration of 1.0 × 10g of standard aqueous solution】 1 determinations. The relative standard deviation is ± 0.8% 4. Park a little water in organic solvent determination of standard samples according to the literature [13 preparation, extraction and poultry samples tested samples of water close to the standard quantitative sampling. Water samples were tested by a standard water sample peak height ratio, calculated as kind of want to test the percentage of water content of towel-type towel C ~ c reported being tested in the moisture content Cheung (neigh) c. A standard sample volume of water birds (%) ht ~ is the peak height test samples of water (cm) h. ~ Standard sample of water peak height (cm) of aniline,[link widoczny dla zalogowanych], ethanol,[link widoczny dla zalogowanych], acetone and ethyl acetate four organic solvents of water towel TN ~. -, And thermal conductivity detector and the results were the more, the results shown in Table 1 wrapped in an organic solvent of water ■ Hu Jing results (compulsory service) aniline sample TcD Law Act c.

At this point, if removed c. 3 replace Rt.. equipment working properly. we can see that c. 3 breakdown short circuit. replace Ca. and R2, equipment return to normal. 2. computer screen Kang stack variable, there ■ shaggy analysis based on experience,[link widoczny dla zalogowanych], resulting in this failure is due to the electronic computer display system thermal properties of components change. At this point, if the back cover to open the screen to screen natural ventilation cooling can be stable again. If, after opening the rear cover is still stable, then adjust the tilt frequency potentiometer circuit board, this time can be observed on the screen clear characters, the instrument is back to normal.
