Automated TVOC Wizard Workflow:
Simplifying Data Processing
What is the TVOC Wizard?
The TVOC (Total Volatile Organic Chemicals) wizard is a software tool that simplifies data handling. The TVOC wizard is optimized for the VDA 278 method and is well-suited for similar TVOC methods that sum the peak areas in a chromatogram and ratio them to an external standard. A single value is easily generated from a complex chromatogram. The simple, intuitive drag-and-drop interface is compatible with any GC-MS system. It does not require additional software, making it independent of the instrument’s GC-MS control software as well.
The TVOC Wizard takes a complicated chromatogram like this and calculates individual results for the VOC, FOG (SVOC), and/or customized ranges for easy material emissions analysis.
TVOC Wizard data processing is automated, freeing up hours, even days, of analyst time.
TVOC Wizard Advanced Features
- Peak deconvolution based on the MC-AR algorithm; others can be used
- Automated Baseline determination
- Use of retention indices (RI)
- Embedded NIST® library search for fast identification of compounds of interest
- Response Factor (RF) determination and method customization
- Automated calibration processing
- Validation mix evaluation for QC reporting
- Customized reporting and data export
Automated TVOC Wizard Workflow: Simplifying Data Processing
- Project data sets are imported (single or multiple file processing)
- Peaks are deconvoluted and processed against embedded NIST Library
- Embedded NIST® 2023 included for high-speed processing
- MC-AR deconvolution algorithm; others can be selected
- Built-in retention indices are used for definitive identification
- Greatly improves identification of unknown/non-target compounds
- TVOC values are calculated
- VOC, FOG (SVOC), or custom ranges
- Method compatible reporting
- Hardcopy/PDF
- Excel/LIMS Exports
- Method compliance:
- Identify and report Non-Target Compounds and TVOC/Total FOG (SVOC) values
- Calculate and report VOC/FOG /Customized values for peaks found and identified
- QC reporting
- Automated calibration and instrument performance verification
- TVOC wizard processes the QC Data
- Reduced frustration/reduced user-to-user variation
- Increased throughput (minutes rather than hours for complex samples)
- Reduced cost per sample
The TVOC Wizard was developed with expert users from major international contract labs in cooperation with GERSTEL staff
• Verified time savings
• Simple, intuitive drag-and-drop interface

TVOC Wizard for Material Emissions or General Indoor Air Quality (IAQ)
- For manufacturers of:
- Building materials, including paints, coatings, and flooring
- Furniture
- Bedding
- Government or contract laboratories that perform IAQ testing
- General chamber testing, including methods ISO 16000-6 and 16000-25
Summary
When running material emissions methods that require peak identification, calculation of total VOC, and total SVOC (FOG), the TVOC Wizard streamlines your workflow, saving valuable time by automating tedious manual data processing and analysis tasks.
This includes the calculation of total peak area, deconvolution, and ultra-fast identification using an embedded NIST library and retention time index.
Processed peak areas can be sorted by compound class, and sample reports are compatible with standard method reporting requirements.
