DVLS3 Smart Hydrogen Sensor from DVLS 

Smart H2 Sensor for GC 

Laboratories using hydrogen as a carrier gas need a reliable safe way to detect hydrogen leaks during GC analysis. Hydrogen is considered the best carrier for GC systems as it provides for fast analysis, high efficiency, reduced costs and prolonged column life. The advantages of hydrogen are clear; but it does have one huge disadvantage: Hydrogen is an explosive gas! An undetected leak can occur with a broken column or a leaking connection which unfortunately can result in an explosion in a GC placing laboratories and their personnel at risk. With the DVLS3 multi-sensor you now have a safe technique to detect a hydrogen leak in GC Laboratories.

PIONA+ by VUV Spectrocopy

PIONA+ analysis made simple

 

The VUV PIONA+ Analyzer is a VGA-100 Gas Chromatography (GC) detector configured for PIONA compound analysis by the VUV PIONA+ method. The VUV PIONA+ method uses relatively simple instrumentation: a gas chromatograph, a standard 30m nonpolar column, and a VGA-100 detector. It is suitable for use with finished gasoline, reformate, reformer feed, FCC, light naphtha, and heavy naphtha samples. VUV PIONA+ utilizes a software engine called VUV AnalyzeTM that provides automated compositional analysis. Bulk concentrations of the hydrocarbon classes of paraffins, isoparaffins, olefins, naphthenes, and aromatics (PIONA) are determined using the VUV AnalyzeTM software package included with the VUV PIONA+ Analyzer. Specific analytes can also be singled out for further characterization, such as individual oxygenates or aromatics belonging to the BTEX complex. VUV PIONA+ is fully compliant with ASTM Method D8071 for finished gasoline samples by GC-VUV.

A push-button solution that features:

  • Single injection PIONA compound class analysis
  • Single 30m Rxi-1ms column
  • 34-minute total analysis time
  • No traps, pre-column tuning, or calibration requirements
  • No special setup
  • ASTM method D8071 Compliance
  • Customizable individual compound speciation including BTEX aromatics

Latest Innovation VUV Spectroscopy

Extended wavelength and temperature

 

The VGA-101 is the latest advancement in vacuum ultraviolet (VUV) detection featuring an expanded wavelength spectrum and a higher allowable maximum operating temperature. It builds on the innovations pioneered by the world’s first benchtop VUV spectrometer, the VGA-100. The VGA-100 is a universal mass-sensitive gas chromatography (GC) detector that provides both qualitative and quantitative data with excellent sensitivity and selectivity. The VGA-101 was designed as a next generation detector that addresses advanced application requirements.

An expanded wavelength spectrum of 120 – 430 nm provides unique selectivity for complex structures such as polyaromatic hydrocarbons (PAHs). The ability to operate the VUV detector as high as 430 °C allows the analysis of high boiling point compounds.

The high frequency data collection in combination with a dedicated flow cell allows this detector to be used for high speed GC and Comprehensive (GCxGC) techniques.

 The ICE-DOOR and COOL-CUBE from SIM

 Oven Cooling system for GC 

You can now carry out chromatographic separations, which need an initial GC oven start temperature between 0 °C and 30 °C, simply and comfortably with the SIM ICE-DOOR.

The cooling of the GC oven is achieved with a compressor cooler, so you no longer need liquid N2 or liquid CO2 which also eliminates handling and the various safety aspects which must be taken into account when using cryogenic liquids.
