This Technical Overview demonstrates the performance of the Agilent 1290 Infi nity Autosampler with increased injection volume capability up to 120 µL.
The standard configuration of the Agilent 1290 Infinity Autosampler has a maximum injection volume of 20 pL. By utilizing the 1290 large volume injection kit (G4216A) with an additional seat capillary, the maximum injection volume can be increased to 120 pL at full power range without major hardware changes.
This document presents data on retention time stability, linearity, and area precision for injections ranging from 20 pL to 120 pL. The results show that relative standard deviations of retention times are typically better than 0.1%, and the relative standard deviation of area precision is typically below 0.25%.
The maximum injection volume can be increased to 120 pL at full power range.
All correlation coefficients are higher than 0.99982.
