A novel application of CMOS webcam camera as a relatively cost
effective detection system in chemical analysis was demonstrated.
The alternative time based detection of chemical reaction could
be performed more automatically with better precision. Continuous
monitoring of the change in migration time during the sample
zone diffusion into the reagent line helped in better selection of the
detection point. Recording of the signal every second is beneficial
for “traceability”. The collected data can be kept for future use as
normally needed in quality assurance in analytical chemistry. The
system has a high potential for various on-site chemical analyses.
