I'm trying to improve the repetitiveness and cleanliness of my VOC Headspace analysis through usage of glass Glass micro capillaries
I got the idea when the local technician used those to test repetitiveness of our GC/MS and GC/FID in the yearly operational qualification test.
If they're good enough for this, they must be constant enough to carry standards, right?
I want to try using them to carry internal standards and calibration standards into headspace vials both for solvent assay tests and for EPA 8260.
There's a bit of added cost involved, but I'm thinking that the advantages overweigh the costs by far, those include:
1) More consistent standard volumes
2) Less, or even, no cross contamination at all from using syringes.
3) Less solvent and standard usage, no need to pre-rinse syringes with standards, no need to post-rinse syringes with clean solvent.
4) Less syringe wear-and-tear by simply using them less.
And I'm sure that there are even more advantages.
What do you think, is this a good solution or am I missing something important?
