In picoscale, the number of particles N in a unit volume is determined from the relation if H stands for a factor of dilution, L is scaling factor of the counter, V is measured volume and E is result display on the digital display.(a) N = HL/VE(b) N = H/LVE(c) N = HV/LE(d) N = HLV/EThe question was asked in an online interview.The query is from Transmission of Digital Audio topic in section Telemedicine Technology of Biomedical Instrumentation

Answer»

Correct answer is (d) N = HLV/E

For explanation: One great advantage of this instrument is that the clogging of the capillary is greatly eliminated by applying a bi-directional FLOW during the MEASUREMENT procedure. The number of PARTICLES N in a unit volume is determined from the RELATION,

N = HLV/E

where

H = factor of dilution

I = scaling factor of the counter

V = measured volume

E = result displayed on the DIGITAL display.
