Project Description

TG-GCMS BALANCED FLOW INTERFACE

The instrument couples a TGA with a GC and MS systems.

TG-GCMS Interface cleanly separates and detects very low leves of molecules in complex mixture developed from the TGA. The EGA generated from the sample in the TGA furnace are transferred through the interface transfer line into the GC where components can be collected on a trapping media in a gas sampling loop or deposited in the head of a column. GC column separates gas mixtures and column generated peaks are detected by the MS.

GC Injection block design avoids capillary cloggings, carry over and any possible cold spots that could compromise the entire analysis. The system allows precise and real-time analysis thanks to the GC instrument which can separate and detect very low levels of material in very complex mixture.

EGA can also be directly sent to MS bypassing the GC.

PRODUCT DETAILS

  • Transfer line with easily replaceable Silcosteel inner-liner which can be heated up to 350°C.
  • Injection Block installed in a separate small oven on the top of the GC, heatable up to 350°C.
  • A unique pre-heated carrier gas system prevent the sample quench inside the injection loop.
  • TGA Adapter or cutomized adapter for your specific needs.
  • Electronic controller to manage temperature and flow, with Mass Flow controller EGA system for evolved gas aspiration, filtration and thermal stabilization (maximum flow rate 200 ml/min).

ADVANTAGES

  • Stable high temperature on the TL and GCMS valves
  • Self-supported TL for more reliable results
  • TL with replaceable inner liner
  • Handy and safe TL outside tube
  • No overlapping events thanks to GCMS combination
  • GC technique improves separation
  • Possibility to use alternative detectors
  • Quantitative & Qualitative output analysis
  • No cold spots and carry over with our valves configuration

TGA-GCMS system has the advantage to switch from GC separtion mode to MS direct mode automatically without any manual changes: TGA-MS Direct Mode – detects and identifies spectra. EGA can be directly sent to the MS detector taking advantage of the selectivity of ions.

Experience a great capability to select a broad range of specific ions and recognize them thanks to a wide range libraries commercially available.
