Los Gatos Research has formally documented and independently validated a software analysis package that enables the company’s water isotope analyzers to simultaneously measure multiple isotopic ratios directly from contaminated samples with accuracy and without sample treatment or purification.

The company’s Spectral Contamination Identifier software has been documented in two independent peer-review journal publications to reliably and accurately measure isotope ratios (δ2H, δ18O) from water samples contaminated with methanol and ethanol. Scientists may now accurately analyze samples obtained from soils, plants or other complex water sources without performing pretreatment procedures.

The effectiveness of the software results from the company’s method of recording fully resolved high-resolution laser absorption spectra, which are always viewable in real time and archived by its isotopic water analyzers. The software performs a smart analysis on these complex spectra to yield corrected isotopic ratios in the presence of contaminants. Other laser-based methods rely on wavelength sampling rather than true wavelength scanning, preventing this type of analysis and requiring purification or chemical treatment of real-world samples such as plant stem water or stagnant groundwater before accurate analysis can be attempted.

The purpose of using rugged and portable laser-based analyzers for direct isotope analysis is to eliminate the complexity, cost and time associated with using traditional lab-bound instrumentation, i.e., isotope ratio mass spectrometry.
