Changing the DLW Holding Loop
Thermo Scientific
With the DLW-2 option, a new DLW holding loop design has been introduced. The DLW-2
holding loop is a high performance loop, which is compatible with the previously used FEP
loop with a separate needle and flow diverter. The DLW-2 holding loop gives better
performance in regard to carryover and low volume injection.
Table 51 shows the differences between the DLW and DLW-2 holding loops.
