  • NIR absorbance measuring instrument with ATR probe
    Patent number: 5739537
    Abstract: In a near infrared absorbance measurement instrument, an attenuated internal reflectance probe comprises a quartz rod having an inexpensive low purity central core surrounded by two high purity quartz layers. Narrow band infrared light is transmitted axially through the outer layer to cause the light to undergo total internal reflection from the inner and outer surfaces of the outer layer. A near infrared light detector measures the light transmitted through the outer layer to obtain a measurement of the absorbance of the fluid in contact with the outer surface of the outer layer without any interference from suspended particles or bubbles in the fluid being measured.
