AOTF-NIR Spectrometer (Laboratory)
Luminar 3070 Benchtop AOTF-NIR Spectrometer
When thinking of AOTF-NIR advantages, most typically think of in-line or at-line advantages. However, the Luminar 3070 Benchtop AOTF-NIR Spectrometer also has advantages because it is an AOTF-NIR instrument, namely:
-
Dry Measurements – reflectance with a rotating dish for powders and granules with almost zero preparation. Single tablets in reflectance are possible. Speed is 5 to 8 seconds per sample.
-
Liquid Measurements – flow cell with pouring the sample into a funnel, allowing good representation of large sample volume, enabling less homogeneous liquids. Speed is 5 to 8 seconds per sample.
-
Transmission Arm with Detector – for single tablets in transmission. Also, seeds in transmission.
-
Immunity to Ambient Light – no need to shield the sample, making it easier to operate.
