We offer a ever growing range of techniques and including various aspects of chromatography, spectroscopy and traditional wet chemistry. As of Autumn 2014 now have the use an Electron Microscope and this is proving very useful to our clients. Apart from morphology we also use this for an approximate elemental composition (like XRF, this is dependent on the matrix).
- Fire debris analysis – looking for accelerant traces using head-space vapour sampling
- Determining the presence of ‘Smoke Taint’ compounds in foodstuffs such as vegetables.
- Oil pollution analysis: CEN15522:2 2006
- Nordtest methods
Also, the identification of trace components / contaminants in
- Polymeric foams
- Coolant system fluids
We can also change from Mass Spectrometer Detector to a Flame Ionisation Detector (FID) as required by different methods (see above). We have two GC-MS systems, one of which includes an auto-sampler.
In December 2017 we acquired our first HPLC. It is currently using a UV detector and has a ternary gradient capability as well as a column oven thus providing high level of customised chromatographic conditions.
The HPLC allow SMS to provide additional methods include dyes in diesel fuels, Poly Aromatic Hydrocarbons (PAH) in foods and can be further expanded with alternative detector modules (Fluorescence, Conductivity, etc. ) in the future.
Examination of a wide range of organic materials including polymer foams. Use of a new sensitive diamond ATR for very small sample quantities.
Sulphate (BaCl2) and Silicate.
