WebAug 1, 2008 · TLC–FID (thin layer chromatography–flame ionization detector in an Iatroscan instrument) has long been used as a rapid and inexpensive way to determine SARA fractions (saturate + aromatic = hydrocarbon, resin (or NSO) + asphaltene = polar) in crude oils and bitumen extracts ( Karlsen and Larter, 1991, Bharati et al., 1994, Bharati et al ... WebJan 1, 1991 · Application of TLC-FID to routine control of precipi- tated asphaltenes and pyrolysates In asphaltene pyrolysis work, it is essential that the asphaltenes are "clean". This is easily monitored, as illustrated in Fig. 8 (a) and (b), which shows the Iatroscan analyses of a "clean" multiply-precipitated [Fig. 8(b)] and "contaminated" singly ...

The thin-layer chromatography-flame ionization detection (TLC-FID) Iatroscan system is a technique which is still being evolved. Quantification with the TLC-FID system relies heavily on the accurate setting up and calibration of the instrument.
WebResults: The TLC-FID technique using mobile phase consist of hexane: acetone (9:1, v/v)has been found to be more effective and less tedious as chromarods were used for performing chromatographic separation. Chlorpyrifos were extracted from the samples by liquid-liquid extraction before the analysis. The method developed can be used to WebIATROSCAN TLC-FID/FPD Dual Detection System. The IATROSCAN MK-7s is thin layer chromatograph measuring sample (s) by means of Flame Ionization Detector (FID). The sample developed on a thin layer quarts rod 'Chromarod' designed for IATROSCAN's exclusive use can be detected by IATROSCAN automatically and quickly.
