Air Analysis Services
Our analytical services support a wide range of air sampling methods which include:

• Environmental / Ambient / Indoor
• Occupational / Industrial Hygiene
• Source / Emissions / Stack

Sampling media can include:

• Gas Bags, Summa Canisters
• Solid Sorbent Tubes & Badges
• Multimethod Sampling Trains

HRC-GC/MS Trace of Volatile Organics Compounds in Air sampled on a carbon sorbent tube. Analysis by Mass Spectrometry enables targeting of specific compounds as well as screening for unknown compounds.

Soils Gas Screening by Flux Chamber, Passive Sampling, Soil Probe & Headspace are available.

Analytical Technology includes a range of high tech, state of the art, equipment and techniques. Typically, analysis is performed by High Resolution Capillary Gas Chromatography - Mass Spectrometry. This offers superior sensitivity & specificity, allowing for a wide range of compounds to be analysed in the one test while reducing the risk of false positives, false negatives and misidentification.


Leeder Consulting have simplified analysis for volatile organics with a screening method which includes an extensive range of Volatile Aromatic and Halogenated Hydrocarbon Compounds.

The standard list of analytes reported in the MA-5 Screen is shown in the table below. Included are most of the commonly analysed volatile organics.

(In addition to MA-5, our MA-8 screen includes Polar Organics Solvents as typically used in the automotive and printing industries. An analyte list for Method MA-8 is available by request.)
