A METHOD OF PERFORMING A TEST, A SUPPORT INSTRUMENT AND A MICROLIQUID SYSTEM COMPRISING SUCH SUPPORT INSTRUMENT

摘要

The invention relates to a method of performing a test of a liquid sample using a microfluidic device with one or more flow paths , a support instrument for use in performing a test as well as a microfluidic system comprising such support instrument. The method of performing the test comprising the steps of introducing the liquid sample into the flow path and subjecting the microfluidic device to at least one linear motion with an acceleration sufficiently high to affect the flow of the liquid sample in the flow path. The flow path e.g. comprises a capillary stop junction, and the method comprises subjecting the microfluidic device to at least one linear motion with an acceleration sufficiently high to force the flow front of said liquid sample to flow over the capillary stop junction. The support instrument for use in supporting a microfluidic device comprises a sustaining arrangement capable of sustaining a microfluidic device, and a motion arrangement capable of subjecting a sustained microfluidic device to at least one linear motion e.g. by subjecting the microfluidic device to a force of at least 0.1 mN. The microfluidic system comprises a microfluidic device and a support instrument.
