Patent ID: 8313948

Claim:
A method for multiplexed sample analysis, comprising: (a) robotically obtaining a first liquid sample from the first of a plurality of sample sources; (b) positioning a switching valve to fluidically couple the first liquid sample to an instrument; (c) delivering the first liquid sample through a first line to the instrument for analysis of the sample; (d) robotically obtaining a second liquid sample from the plurality of sample sources; (e) switching the switching valve to fluidically couple the second liquid sample to the instrument; (f) delivering the second liquid sample through a second line to the instrument for analysis, a second control valve is located within the second line; (g) positioning a first control valve located in the first line to communicate liquid between the first line and a wash channel, the wash channel connected to a wash container including cleaning fluid, thereby cleaning the first line while the second line is delivering sample to the instrument; and (h) positioning the second control valve located in the second line to communicate liquid between the second line and the wash channel, the wash channel connected to the wash container including the cleaning fluid, thereby cleaning the second line while the first line is delivering sample to the instrument.
