Standard Practice for Describing and Measuring Performance of Laboratory Fourier Transform Near-Infrared (FT-NIR) Spectrometers: Level Zero and Level One Tests
standard by ASTM International, 01/01/2013
1.1 This practice covers two levels of tests to measure the performance of laboratory Fourier transform near infrared (FT-NIR) spectrometers. This practice applies to the short-wave near infrared region, approximately 800 nm (12 500 cm -1) to 1100 nm (9090.91 cm -1); and the long-wavelength near infrared region, approximately 1100 nm (9090.91 cm -1) to 2500 nm (4000 cm -1). This practice is intended mainly for transmittance measurements of gases and liquids, although it is broadly applicable for reflectance measurements.
