Second-Dimension Temperature Programming System for Comprehensive Two-Dimensional Gas Chromatography. Part 1: Precise Temperature Control Based on Column Electrical Resistance

Hei Yin J. Chow et al.

Summary: A second-dimension temperature programming system (DTPS-D-2) for GC xGC was introduced and characterized. The system utilized a stainless-steel capillary column as the heating element and sensor, and an Arduino Uno R3 microcontroller for control. Comparisons were made with a diesel sample for (2) n (c) and (2) R (s), and with a perfume sample for within-day and day-to-day reproducibility. The (2) n (c) was improved by 52% with the (DTPS)-D-2 compared to the secondary oven. The GC xGC system utilizing the (DTPS)-D-2 exhibited low RSD for retention times and peak area.
