GC / GC-MS Reference Standards & Sample Preparation
Support reliable volatile and semi-volatile organic analysis with suitable calibration standards, internal standards, extraction procedures and matrix-aware quality control.
Typical Sample Types for GC / GC-MS
The appropriate analytical method depends on the sample matrix, target analytes, concentration range and required accuracy.
Volatile Organic Compounds
VOC analysis in environmental, industrial and indoor-air related applications.
Petroleum & Hydrocarbons
Hydrocarbon profiling, fuel-related contaminants and petroleum analytical methods.
Pesticides
Target compounds in food, water, soil and agricultural samples.
Solvents & Chemicals
Purity, residual solvent and process-chemical applications.
Forensic / Toxicology
Target organic compounds and screening applications using validated methods.
Flavor / Fragrance / Food
Volatile compounds, aroma profiles and selected contaminants in food-related matrices.
Prepare the Sample for Reliable Measurement
GC and GC-MS sample preparation depends strongly on volatility, polarity, concentration and matrix. The objective is to transfer the target compounds into a clean, injection-compatible form while minimizing losses and interferences.
Choose the Extraction Approach
Use direct dilution, liquid-liquid extraction, SPE, headspace or other validated preparation routes.
Control Recovery
Use surrogates, spikes and recovery checks where the method requires quantitative extraction.
Add Internal Standards
Use suitable internal standards to compensate for injection and instrumental variability.
Protect the System
Remove non-volatile matrix components and particulates before injection when appropriate.
How to Select the Right Reference Material
Reference material selection should follow the real sample matrix, analytes, working range and intended use of the material.
Match the Target Compounds
Select certified standards containing the exact analytes required by the method.
Check Solvent Compatibility
Use standards prepared in a solvent compatible with the method and instrument configuration.
Cover the Working Range
Prepare calibration levels that bracket routine sample concentrations.
Include QC Standards
Use second-source or independent QC materials to verify calibration and method performance.
Reference Material Options
Availability depends on analyte, matrix, concentration range, certification scope and manufacturer portfolio.
Common Standard Types
- Single-compound organic standards
- Multi-component calibration mixes
- VOC standards
- Pesticide standards
- Hydrocarbon / petroleum standards
- Internal and surrogate standards
Relevant Manufacturers
Final selection should be based on the exact method, matrix, analyte range and certificate requirements of your laboratory.
