Gas Chromatography / Mass Spectrometry (GC/MS)
ALS specializes in analysis of both volatile and semi-volatile organic compounds to meet standards for drinking water and wastewater regulation as well as hazardous waste characterization. We utilize both GC and GC/MS instrumentation to analyze you sample and determine the concentration of hundreds of individual organic compounds. Our sample batches are structured to ensure integrity in every sample. The sample batches include:
- blank QC at the beginning of each run to monitor and prevent crossover contamination
- primary and surrogate standards to measure instrument performance and recovery
- secondary standards to assure integrity of the primary standards
- continuing calibration verification standards to ensure quality throughout an entire batch
Inductively Coupled Plasma / Mass Spectroscopy (ICP/MS)
Our laboratory has vast experience in analyzing drinking water, wastewater, hazardous waste, soils and biological samples for trace metals to meet Regulatory requirements such as Title 21, Title 22, RCRA classification, Self-Monitor Reporting, NSF-372 and more. Truesdail houses multiple ICP and ICP-MS instruments enabling us to analyze high volume of samples for various types of industry requirements including Title 22 metals, lead content in plumbing products and cobalt levels in horse racing samples. To assure the utmost quality data to our clients, every batch undergoes rigorous internal quality control requirements, including a multitude of calibration standards being run with each set of samples to ensure instrument performance, blanks to mitigate potential contamination, primary and secondary standards, continuing verification standards, blank spikes, sample duplicates and sample matrix spikes in every batch which are digested and analyzed along with our client samples in order to meet our standard of quality.
All Wet and General Chemistry analysis performed by ALS are analyzed with Quality Control samples meeting or exceeding the EPA or Standard Water and Wastewater Methods requirements. Our SOP’s include guidelines that are requisite to these approved methods and include, but are not limited to the analysis of blanks, blank spikes, sample duplicates, matrix spikes, calibration standards and more to ensure quality data and best practices.
