GENESITE Environmental Protection Technology Co., Ltd.
HY01
The GNST-HY01 infrared spectrophotometer is used to determine the oil after the water sample is extracted with tetrachloroethylene under the condition of pH ≤ 2; the petroleum is determined after the extract is adsorbed with magnesium silicate to remove polar substances such as animal and plant oils. The content of oil and petroleum is calculated based on the correction coefficient by the absorbance A2930, A2960 and A3030 at the wave numbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-H bond in CH3 group) and 3030cm-1 (stretching vibration of C-H bond in aromatic ring); the content of vegetable oil is the difference between the content of oil and petroleum.
• The whole operation is odorless, friendly to operators and the environment, and pollution-free.
• Fast detection speed, short stabilization time, and it only takes 10 seconds to detect a sample.
• Low reagent usage: solves the problems of large amounts of extractants and samples, strong odor, and complex purification and cleaning.
• It can be used on-site and in the laboratory, and is in an aluminum alloy box that can be carried to the site for testing.
• Low detection limit and high accuracy.
