Abstract

High-Performance Thin Layer Chromatography (HPTLC) is one of the revolutionary techniques that has the advantage of full optimization, minimum sample preparation, automation and hyphenation. Using HPTLC system is used frequently in forensic science for analysis of new drugs, poison, fingerprints, etc. In this paper, we study the major and minor faults of two units of HPTLC system by considering the fact that for minor and major faults, system goes to the partial failure and complete failure, respectively. On occurrence of a fault in a system, either the technician carries out the system to repair or if technician is busy the unit has to wait for repair. Systems parameters are derived by utilizing regenerative point graphical technique. Experimental results are performed to analyze system availability, server visit, busy period and profit. Graphical representations are shown for better understanding of the proposed technique.
