Koehler K Portable Fuel Property Analyzer (ASTM E) | Labequip
These practices are applicable to analyses conducted in the near infrared NIR spectral region roughly to nm through the mid infrared MIR spectral region e155 to cm No other units of measurement are included in this standard. Criteria for validating the performance of the calibration model are described. Advanced VA systems with high-performance viva software for determining traces of heavy metals with polarography and voltammetry with high sensitivity.
Application news, practical tips for the laboratory, and more. The user is cautioned that typical and best practices for multivariate quantitative analysis using other forms of spectroscopy may differ from practices described herein for mid- and near-infrared spectroscopies. Portable voltammetric analyzer for the determination of trace levels of arsenic, mercury, and copper in water.
Standard Practices for Infrared Multivariate Quantitative Analysis
While these surrogate methods generally make use of asym multivariate mathematics described herein, they do not conform to procedures described herein, specifically with respect to the handling of outliers. Users will find these practices to be applicable to basic aspects of the technique, to include sample selection and preparation, instrument operation, and data interpretation.
Active view current version of standard.
Analysis is obtained in seconds using only a 2 mL fuel sample. While sampling methods and instrumentation may differ, the general calibration methodologies are equally applicable to mid-infrared spectroscopy.
