专利汇可以提供IMPROVED METHOD FOR DILUTING A LIQUID TEST SAMPLE AND COMPUTER CONTROLLED DILUTING APPARATUS专利检索,专利查询,专利分析的服务。并且A method for the pick-up and delivery of a liquid test sample and diluent therefor by a single syringe (31) having a syringe valve (21) for placing the syringe barrel in fluid connection with either a diluent pick-up line or a sample pick-up line (29). The method is comprised essentially of the steps of priming the apparatus, picking up the diluent through the diluent pick-up line and thereafter with a continuing downward stroke of the syringe plunger (35) picking up a percentage volume of liquid sample. Preferably, an air bubble (81) is picked up in the end of the sample pick-up line before the sample pick-up cycle. After the full downward stroke of the syringe plunger, the diluted sample is delivered by depressing the plunger to its zero volume setting. An apparatus is provided having a computer controlled syringe plunger drive (49) which includes a zero volume switch (61), and a computer controlled syringe valve (21) having branch ports (23, 25, 26) adapted to be connected to a diluent (27) and a sample pick-up (29) line. The computer control sequences the plunger drive and the syringe valve to pick up diluent and sample and deliver diluent and sample as above-described.,下面是IMPROVED METHOD FOR DILUTING A LIQUID TEST SAMPLE AND COMPUTER CONTROLLED DILUTING APPARATUS专利的具体信息内容。
