Gas Chromatograph - GC Analyzer - 450°C Column Oven - 120°C/min Heating Rate

The Master Science Gas Chromatograph is a laboratory GC built for the routine separation and measurement of volatile and semi-volatile compounds. A redesigned injection system improves the accuracy and repeatability of each injection, while an upgraded electronics platform speeds up data handling and keeps the instrument stable during long working days.

Up to three inlets and four detectors can be fitted to the same mainframe, so one instrument can be configured for natural gas, refinery gas, LPG, solvent residue and general quality control methods.

Key Benefits

• Repeatable injections: the reworked inlet design keeps sample transfer consistent from run to run, which shows up as tighter peak area repeatability.
• Faster turnaround between runs: a 120 °C/min ramp and cool-down from 450 °C to 50 °C in under five minutes shorten each analytical cycle.
• One mainframe, many methods: the Master Science Gas Chromatograph accepts three inlets and four detectors, so FID and TCD work can share a single instrument.
• Easy daily operation: method parameters and instrument status are set and checked directly on the 7-inch touchscreen.
• Long service life: the upgraded circuit system and sturdy construction are designed for continuous operation in demanding labs.

Laboratories that run both GC and LC methods can pair this unit with the Master Science HPLC liquid chromatography system to cover volatile and non-volatile analytes.

Common Laboratory Problems and How This GC Helps

Typical GC issues in busy laboratories and how the Master Science Gas Chromatograph deals with them:

• Poor peak area repeatability: the optimised inlet design improves injection consistency.
• Long waits between runs: fast oven heating and cooling reduce cycle time.
• Separate instruments for each detector type: up to four detectors run on one mainframe.
• Unstable baselines over long sequences: low FID and TCD noise and drift support reliable integration.
• Complex software for new staff: the touchscreen interface keeps routine tasks simple.
