1.	In sample holders, for such applications, a 50 cm path-length with about a ________ volume cell is employed.(a) 0.3 ml(b) 3 liters(c) 0.3 liters(d) 3 mlThe question was asked in examination.This is a very interesting question from Methods of Monitoring Foetal Heart Rate in portion Foetal Monitoring Instruments of Biomedical Instrumentation
Answer» The correct option is (C) 0.3 liters To explain I would say: Studies of DILUTE or weakly-absorbing LIQUID samples, or of samples where trace components must be detected, require a cell with a long path-length. For such applications, a 50 cm path-length with about a 300 ML volume cell is EMPLOYED.
