2、ing such diseases,and under appropriate circumstances, results are used for diagnostic purposes.In recent years, automation in clinical chemistry has progressed with a change from rigid to very flexible instruments. Auto

3、mation of clinical instruments has brought about a revolution in the field of medical instrumentation. It has reducedthe load on clinical laboratories to a great extent by reducing the time taken in the test and minimizi

4、ng the involvement of laboratory staff. Instrument developed is classified as semiautomated analyser [2] and has advantages of precision and accuracy. These systems are used in hospitals to test various blood biochemical

5、 parameters. All primary health centres, community health centres, and district hospitals are the potential users of this machine.2. MATERIALS AND METHODS2.1. The instrument(i) Design principleThe instrument is designed

6、using the principle of absorbance transmittance photometry. According to Lambert and Beer’Figure 1: Schematic of Lambert and Beer’s law.Figure 2: Relation between percent transmission and concentration.law [3], when mono

7、chromatic light is passed through coloured solution, the intensity of the transmitted light decreases exponentially with the increase in concentration of the absorbing substance. The value of absorption of light energy i

8、s dependent on the number of molecules present in absorbing material and the thickness of the medium. Thus,intensity of light energy leaving the absorbing substance is used as an indication of concentration of that parti

9、cular substance.As shown in Figures 1 and 2, if I0 is the intensity of incident light in coloured solution and It is the transmitted light, then according to this lawIt = I0e- kct
