Organic compounds analysis is very challenging when compared to trace metals analysis on account of thousands of potentially toxic organic compounds or contaminants relative to limited number of metals that could be present in samples. EPA regulates Organics contamination at ppb (parts per billion) levels in contaminated samples of soil, water, air, including agricultural and chemical products and requires their identification and quantification.
Organics analysis is also routinely required during various stages of product development in manufacturing including in-process and finished goods stages to identify impurities, report purity, assay and monitor product quality.
LSAI has HPLC coupled with UV and fluorescence detectors and several GC/MS instruments along with FID and ECD detectors to detect, identify and quantitate several types of Organics in various types of materials and matrices.
LSAI has trained scientists proficient in method development and validation. We can perform compendial based analysis and comply with regulation procedures during the analysis.
QA/QC protocol specified is adopted during analysis. Proprietary analytical procedures developed by the lab personnel are investigated thoroughly before application with respect to accuracy, precision, sensitivity, repeatability and applicability to samples matrices. Internal and surrogate standards are routinely used to check efficiency of extraction and instrument performance in GC analysis; recoveries of spikes should be >80% for high confidence in the resulting analysis. Blanks and replicates (1 in 10 samples) are also used to assess contamination and precision of analysis. Multipoint standard calibrations are used to assess the linear range of detector response, and to accurately determine the detection limit of the method.
