No.
I've had my trimix ticket for two years and whilst I'd buy a He analyser if the price was right, I'd never spend £500 on one. O2 analysis is critical, but helium can be way off without making much difference.
When I've blended my own mix and had the opportunity to analyse it, it's always been 'there or thereabouts' even when I've been blending on top of left-over mix.
As long as my calculations are correct, if the O2 comes out right; the He will be right too.
