Fast Determination of Maturity and Fineness by NIR with a Diode-Array HVI. Part 2. Reference Method

J.G. Montalvo, Jr. and S.E. Faught


 
ABSTRACT

High precision headspace resistance standards (HRS) were developed at SRRC for the Micromat model of the fineness and maturity tester (FMT). HRS are stable, physical standards used to create precise differential pressures when air is drawn through the device. Micromat calibration PL and PH air flow rates are "transferred" to the HRS. Routine analysis of 36 cottons from Stonveille, MS is presented based on the transferred calibration. Elimination of short-term drift is demonstrated and confirms earlier work.
