Abstract
The method of diluting a fluid sample for analysis in a sample analysis system includes the provision of an aspiration probe with two interior sections. The first interior section of the probe has a first diameter and is proximate the aspiration opening of the probe. The second interior section of the probe has a second diameter of greater magnitude than the first diameter and is located distally of the first section. The probe aspirates in consecutive order selected amounts of fluid sample and diluent into the first interior section of the probe. The fluid sample and diluent are mixed in the second interior section of the probe by moving the sample and diluent back and forth in the second interior section a predetermined number of times. The back and forth movement of diluent and fluid sample in the second interior section of the probe provides substantially uniform mixing of the sample and diluent. The use of a Teflon.RTM. probe coated with fluorocarbon oil eliminates the risk of cross-contaminating the sources of fluid sample and diluent.
