ASTM D5134 Petroleum Naphthas through n-Nonane by Capillary GC
KN-5134 GC for Detailed Analysis of Petroleum Naphthas conforms to ASTM D5134 Standard Test Method for Detailed Analysis of Petroleum Naphthas through n-Nonane by Capillary Gas Chromatography and ASTM D6733 Standard Test Method for Determination of Individual Components in Spark Ignition Engine Fuels by 50-Metre Capillary High Resolution Gas Chromatography. A representative sample of the naphtha is introduced into a gas chromatograph equipped with a methyl silicone bonded phase fused silica capillary column. Helium carrier gas transports the vaporized sample through the column in which the components are separated. Components are sensed by a flame ionization detector as they elute from the column. The detector signal is processed by an electronic data acquisition.

Gel Permeation Chromatography (GPC)
GPC gel purification system has many advantages such as high purification rate, simple operation, convenient maintenance, safety and reliability. It is mainly used in the pre-treatment and purification process of samples for the detection of pesticide and veterinary drug residues, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls. It is widely used in the fields of agricultural products, food, environment and life sciences.

EN14110 Methanol Content In Fatty Acid Methyle Esters By GC
the sample is heared at 80℃ in a hermetically sealed vial to allow desorption of contained methannol into the gas phase.when equilibrium is reached,a defined part of the gas phase is injected into a gas chromatograph,where methanol is detected with a flame ionisation detector.normally methanol is the only peak in the chromatogram.
