High-Resolution Laboratory
ALS has two Waters Micromass AutoSpec-Premier, two AutoSpec-Ultima and VG70S high resolution mass spectrometers. The Waters Micromass AutoSpec Premier and Ultima instruments are considered to be the optimal choice for ultra low-level trace detection applications such as the analysis of:
- Dioxins
- Furans
- PCB congeners
- Polyaromatic hydrocarbons (PAHs)
- Polybrominated diphenyl ethers (PBDEs)
Our detection limits are now running 10 - 100 times lower than with the older instruments and are among the lowest in the industry.
The laboratory performs these analyses on a variety of sample matrices:
- Food products
- Food additives
- PUF cartridges
- XAD resins/filters
- Household dus
- Wipe samples
- Sediments
- Animal/marine tissues
- Paper, incinerator ash
- Soil, waste water
- Drinking water
- Solid waste
- EPA 8290
- EPA 8280A
- EPA 1668 (PCB congeners)
- EPA 1613B
- EPA TO9 (ambient air)
- EPA 23 (stack testing)
Technical consulting on dioxin and other recalcitrant compounds is also available. New strides are being made with the addition of method CARB 429 for very low levels of polyaromatic hydrocarbons (PAHs) and the analysis for polybrominated fire retardant chemicals like polybrominated diphenyl ethers (PDBEs).
