I'm using GC7890B with 7693 autosampler and Agilent syringe 5188-5246. That’s a 1microlitre syringe gauge 23.
Fairly standard conditions and I'm confident there are no chemistry issues.
My fundamental question is should it be possible to achieve good RSD’s with this small injection from the one microlitre syringe or is this outside the performance of this syringe/below the minimum injection volume for this syringe. I believe it should be possible to inject down to 10% of a syringe’s volume, e.g 1microlitre from a 10microlitre syringe, 0.5microlitre from a 5microlitre syringe and so on. Does this rule not hold for the one microliter syringe?
Am I trying to achieve the impossible with a 0.2microlitre injection from a 1microlitre syringe??
Any advice you can give would be greatly appreciated.
Kind Regards
Steve
