VUV Detector for TRACE 1600 Series GC

Precision, clarity, and confidence from VUV spectroscopy in GC

VUV detectors paired with the Thermo Scientific TRACE 1600 Series GC conquer the challenge of complex mixtures, co-eluting compounds, and isomer differentiation for accurate hydrocarbon speciation, impurity detection, and trace-level detection.
 

Gas Chromatography (GC) is evolving, and VUV (Vacuum Ultraviolet) technology is at the forefront of this transformation. Now available on the TRACE 1600 Series GC, VUV spectroscopy, through VUV Analytics VGA-100 detector and the LUMA detector, provides accuracy in hydrocarbon speciation, impurity detection, and trace-level analysis.

 

Greater accuracy, automation, and confidence in your GC analysis

Traditional GC detectors struggle with complex mixtures, co-eluting compounds, and isomer differentiation. VUV spectroscopy overcomes these limitations by using absorption-based detection, capturing unique molecular fingerprints for each compound.

Transforming hydrocarbon analysis with GC-VUV technology

Join us for an insightful webinar to discover how Vacuum Ultraviolet (VUV) technology is transforming Gas Chromatography (GC) analysis of complex mixtures, delivering significant benefits to your laboratory operations.

How VUV technology works

VUV detection provides qualitative and quantitative spectral information for most gas phase compounds. 

Broad-spectrum absorption: VUV detectors measure how molecules absorb light in the vacuum ultraviolet range (120–240 nm), revealing unique spectral signatures.

Automated compound ID: To reduce errors and improve analysis speed, VUV software automatically deconvolutes overlapping peaks. unlike traditional GC detectors.

Quantitative and qualitative insights: VUV enables compound identification and quantification in a single run by analyzing complete spectral data.

Principle of operations

Principal of operations
  1. Sample injection in the GC: A sample is injected into the GC system and separated into its components as it travels through the GC column.
  2. Elution from the analytical column: The separated components elute from the GC column and enter the VUV detector.
  3. VUV light source: A deuterium lamp as VUV light source emits light in the vacuum ultraviolet range (typically 120-200 nm).
  4. Flow cell: The eluted components pass through a flow cell where they are exposed to the VUV light.
  5. Analytes absorption of VUV light: As components pass through the flow cell, they absorb VUV light at specific wavelengths. Each compound has a unique absorption spectrum in the VUV range.
  6. Analytes detection: Photodiode array detector measures the intensity of the transmitted VUV light. The decrease in light intensity corresponds to the absorption by the analytes.
  7. Data processing: Detector sends the signal to a data processing system, which converts the absorption data into a chromatogram.

VUV for petrochemical and refining

Elevate your gas chromatography detection capabilities with vacuum ultraviolet spectroscopy through dedicated GC-VUV analyzers for fuels. Experience superior excellent sensitivity, selectivity, and ease of use, tailored to meet the needs of fuels characterization. To analyze finished fuels and feedstocks using traditional methods requires multiple analytical techniques, complicated hardware set up, extensive analysis time, and prior knowledge of the samples being analyzed, leading to wasted time on re-analysis.

  • PIONA analysis: Accurately classify paraffins, isomers, olefins, naphthenes, and aromatics with automated deconvolution for fast, confident hydrocarbon speciation and group type analysis in complex fuels.
  • Fuel quality control (ASTM D8071): Ensure compliant, efficient fuel characterization using VUV’s spectral fingerprints, delivering fast, automated analysis for gasoline and other fuel blends.
  • Sulfur & nitrogen speciation: Detect and speciate sulfur and nitrogen compounds at trace levels in fuels, ensuring regulatory compliance and protecting product quality.

VUV for pharmaceutical and chemicals

With unique selectivity for trace analysis, GC-VUV technology ensures accurate and reliable results for impurities detection at part per billion levels, i.e. nitrosamine, in complex matrices. GC-VUV technology is ideal for residual water analysis, as well as solvent impurities in one single analytical run, saving time and resources while maintaining high sensitivity and selectivity.

  • Residual solvent analysis: Faster, more sensitive detection of residual solvents, ensuring compliance with USP <467> and reducing reanalysis with precise, automated detection.
  • Impurity profiling in APIs: VUV absorbance provides greater selectivity and lower detection limits than traditional GC detectors, ensuring reliable impurity profiling in even the most complex APIs.
  • Trace-level contamination detection: Identify unknown contaminants at low levels in pharmaceuticals, chemicals, and environmental samples with enhanced selectivity and sensitivity.
