Introduction to ASTM E168
These procedures are meant for all infrared spectrophotometers. These exercises will give beginners an overview of calculation, operation, and preparation methods. When rarely-used skills are required, experienced individuals can employ these practices as a review. ASTM E168 provides a thorough framework that encompasses the most common methods used in the field of quantitative infrared analysis. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E168 tests for our clients. The measurement of absorbance at particular wavenumbers is the basis for infrared quantitative analysis, which uses this information to correlate target compound concentrations. By guaranteeing the development of a dependable and linear correlation between absorbance and concentration, this improves the precision and accuracy of quantitative measurements.
ASTM E168 Test Method
| Quantitative Infrared Measurements | Commonly used tools for quantitative infrared analysis include gratings, filters, prisms, and interferometers. |
| Single-Compound Analysis | The foundation of quantitative spectrometry is the Beer-Bouguer-Lambert law, sometimes known as Beer’s law. |
ASTM E168 Test Specimens
| Specimen Detail | Single-component or multicomponent compounds can be used |
| Specimen Size | To reduce the effects of dispersion in refractive index, spectrometer nonlinearity, and molecule interaction on the linearity of the absorbance-concentration relationship, analytical wavenumbers are used. |
