Routine Analytical Services

Micro-Scan Services, Inc. uses an HP 5890 GC with an HP5970A Mass Selective Detector to provide GC/MS services. The mass range is from 2 to 800 AMU. The sensitivity is dependent on the compound of interest, but the equipment specification is for a 20:1 signal-to-noise ration trace with 1 nanogram (10-9 grams) of methyl stearate delivered to the detector. This translates to about 100 nanograms injected when using a split-mode injector. Data can be obtained in the full scan mode to provide the mass spectra of peaks or, for increased quantitative precision and sensitivity, in single ion monitoring (SIM) mode, where for known materials, up to eight different M/e values can be monitored.

APPLICATIONS

GENERAL GC/MS FOR MAJOR COMPONENTS ANALYSIS
We can analyze gases and liquids or solids with volatile components. The sample size will vary with analytical requirements from several milliliters for a gas sample to milligrams of material for liquids and solids.
MONITORING OF INCOMING RAW MATERIALS
We can provide analysis of raw materials provided by your suppliers. Contracts for continuing analyses can result in substantially lower prices.
CONFIRMATION OF GC ANALYSES
Frequently, a laboratory monitoring processes by GC alone my encounter unknown peaks. If provided with a GC trace from your instrument, along with a description of the column, instrumental conditions used, and identification of known components, we can economically provide fast turnaround on mass spectra of the unknown components. The service includes matching of the spectra to the NBS mass spectral database.
STATIC HEADSPACE ANALYSIS
Analysis of volatiles in a sealed container at normal or elevated temperatures.
COMPETITIVE ANALYSIS
Extractions and separations on commercial products followed by GC/MS can be used to maintain competitive positions by determining changes in product compositions and new materials in your market. Analysis of copycat products can help determine if your patents are being infringed, and the data can be used to support legal action.

THINGS WE DON'T DO
Environmental analysis, hazardous waste determinations, water quality, clinical samples, or illegal drugs. We can provide names of certified laboratories for environmental and hazardous waste work if you need that service.
