Sampling equipment, cotton dust

Cotton dust sampling is a plant site test, normally involving unsophisticated field equipment, ever-changing plant conditions, and technician-level labor in performing many functions. However, with adequate equipment and attention to technique, we have found that good quality data can be obtained for each survey. The purpose of this paper is to share with you some of the instrumentation, equipment modifications and techniques we have studied and employed to obtain vertical elutriator (VE) data with average coefficients of variation less than 10%. 

Experience and common sense have helped us to refine the procedures for cotton dust sampling to obtain accurate and representative samples. The low coefficients of variation among multiple VE samples indicate that proper attention to equipment and techniques does result in quality data.
