Product Description

1. Applicable boiling range: petroleum products or distillates of 55~550ºC boiling range distribution 

such as fuel, kerosene, diesel, lubricants, wax oil etc. On this chromatographic condition tested sample components can all show the peaks. It adopts area normalization method to fix quantity. It complies to SH/T 0558-2002 and ASTM D2887standard.

2. Applicable boiling range: crude oil of initial boiling point~538ºC boiling range distribution. Get distribution proportion of fuel, diesel, kerosene, heavy oil. Since the heavy components above 538ºC can not show peak, it adopts incremental internal standard method and complies to ASTM D5307 standard.

3. Applicable boiling range: petroleum products or distillates of 55~680ºC boiling range distribution. 

On this chromatographic condition tested sample components can all show the peaks. It adopts area normalization method to fix quantity.
