KN-2409 GC for Determination Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol. A gas Chromatograph determines the glycol impurities in Mono-, Di- Tri- and Tetraethylene Glycol (MEG, DEG, TEG and TeEG) in the range of 5 to 3000 mg/kg. Knowledge of the impurities is required to establish whether the product meets the requirements of its specifications.
KN-2409 GC for Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol
Overview
KN-2409 GC for Determination Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol. A gas Chromatograph determines the glycol impurities in Mono-, Di- Tri- and Tetraethylene Glycol (MEG, DEG, TEG and TeEG) in the range of 5 to 3000 mg/kg.
Summary
A sample s o l u t i o n was prepared by mixing approximately 5 g of commercially available propylene glycol in 100 mL of methanol. The chromatogram obtained using a 1 μL injection is shown in Fig. 3. Supplement Ⅱ also specifies as follows: The amounts of ethylene glycol and diethylene glycol present in a sample solution are not to exceed 0.1 % respectively based on the standard solution area values. Following elution of the solvent, the area values are to be measured over a range about three times the retention time of propylene glycol. The peak areas of peaks other than propylene glycol, ethylene glycol and diethylene glycol in the sample solution must be no greater than 0.1 %, respectively, calculated by the area percentage method, and the total peak area of all peaks other than propylene glycol must be no greater than 1.0 %.
Features
1. Adopts imported 10.2 inch (1280X800) color touch screen
2. 8 channels control the temperature, 8 external events
3. Be able to set flow rate, pressure, temperature and detector parameters on the PC (Function depends on the exact model)
4. Logarithmic amplifier, no flat solvent peak
5. Screen real-time spectrum display, be able to display three-channel spectrum simultaneously
6. FID automatic ignition
7. 8 channels temperature control, if any channel overtemperature, the system will stop heating and alarm automatically
8. Program heating: 8 steps, be able to do infinite steps heating via programming
9. Every flow rate can be displayed on the screen, no need the pointer pressure gauge
10. At lease3 detectors signal acquisition simultaneously
11. Hydrogen leak protection and carrier gas saving mode: The tester will automatically enter the low-split mode after the injection, which greatly reduces the consumption of carrier gas and operating cost
12. Only one cable can control the tester and data signal output
13. Advanced EPC system, maximum 12 channel electric flow control modules are available
14. Be able to set the related parameters via the workstation
15. Two-way communication between screen and counter control workstation
16. Adopts imported EPC module
