Abstract
A multiple loop sample introduction system comprises a valve assembly including a sample collection valve and a sample introduction valve. First and second sample loops are in fluid communication with the sample collection valve and the sample introduction valve to receive aliquots of liquid samples to be introduced into a nebulizer. The valve assembly is operable to port a first aliquot into the first sample loop, while porting a second aliquot received in the second sample loop for introduction into the nebulizer.
