Re: Split baseline and streaks
The column set is as follows: HP5 (30 m x 0.25 mm, 250 µm) x BPX50 (1.2 x 0.25, 250 µm) connected with a 1 m, 0.25 mm loop. Modulation period 7000 ms and hot jet duration 350 ms. GC oven temperature 60 oC start with 4 oC/min ramp to 310 oC. Hot jet is constant +50 oC offset (110 - 360 oC). The loop ...
