美***Wilks公司H水中含油分析儀 比較表 | |||
| Model CVH | Model HATR-T2 | Model CH |
*小探測(cè)極限(oil in water) | 2 ppm | 8 ppm | 40 ppm Note: Models CVH & HATR-T2 are the most widely used for all types of oil-in-water measurements. |
*小探測(cè)極限 (TPH in soil) | 10 ppm | 40 ppm | 200 ppm |
萃取溶劑 | Perchloroethylene, Freon-113, S-316 | Hexane, Pentane, Vertrel MCA | Hexane, Pentane, Vertrel MCA |
可測(cè)量的烴種類 | Measures all hydrocarbons | Measures hydrocarbons with a boiling point higher than the solvent - volatile hydrocarbons will be evaporated along with the solvent. | Measures hydrocarbons with a boiling point higher than the solvent - volatile hydrocarbons will be evaporated along with the solvent. |
重復(fù)性 | +/- 1 ppm | +/- 2 ppm | +/- 4 ppm |
典型應(yīng)用 | ? Oil in Water/Wastewater ? Oil in Produced Water ? Fats, Oil & Grease (FOG in Wastewater Discharges ? TPH in Soil ? Samples with Light-End Volatile Components | ? Oil in Water/Wastewater ? Oil in Produced Water ? Fats, Oil & Grease (FOG in Wastewater Discharges ? TPH in Soil | ? Very High Levels of Oil in Water ? TPH in Soil |
其它 | Solvents are heavier than water and require a separatory funnel or inverted vial with a septa cap to collect a solvent sample. | Solvents are lighter than water and solvent sample can be collected from the top of the container. | Solvents are lighter than water and solvent sample can be collected from the top of the container |
然而具體到每***個(gè)型號(hào)其測(cè)量原理又有所不同,Model CVH是采用重于水的溶劑來萃取樣品中的油脂,例如氟利昂,四氯乙烯,S-316,AK-225或其他在紅外波段透明又重于水的溶劑。而Model HATR-T2和Model CH則是采用輕于水的溶劑來萃取樣品中的油脂,例如正己烷,戊烷或Vertrel MCA或其它在紅外波段透明又輕于水的溶劑。
測(cè)量原理上決定了CVH可以測(cè)量樣品中所有的烴類物質(zhì)比例,而HATR-T2和CH只能沸點(diǎn)高于所選溶劑的測(cè)量比例,沸點(diǎn)低于溶劑的成分會(huì)在取樣和測(cè)量過程中揮發(fā)。CVH和HATR-T2***般都在實(shí)驗(yàn)室中使用,而CH和HATR-2更加牢固,適合測(cè)量高濃度的石油烴/油脂樣品,因此更適于于野外現(xiàn)場(chǎng)的應(yīng)用。
從測(cè)量范圍和測(cè)量精度上來看,CVH對(duì)于水中油脂(TOG)*小探測(cè)極限為2ppm,對(duì)于由中的石油烴(TPH)的*小探測(cè)極限為10ppm。HATR-T2測(cè)量TOG和TPH的*少量分別為8ppm和40ppm。而CH測(cè)量TOG和TPH的*小量分別為40ppm和200ppm。設(shè)備的重復(fù)性也是CVH*優(yōu),重復(fù)性為±1ppm,HATR-T2和CH的重復(fù)性分別為±2ppm和±4ppm。
