Custom Standard manufacturer?

[JesseG]

Can anyone point me to a lab that will make custom standards for GC?

Specifically-> 0.2% L-lactide monomer in chloroform.

We can supply the monomer if needed

TIA

I liked dealing with them when you were there. Since they were acquired by Sigma they are too much of a "big" company.

We are checking there but response is somewhat slow

I've made requests from Restek and Supelco. Most recently I requested a quote for a ~50 analyte residual solvent mix from both. The Restek quote was 4X the Supelco quote, because Restek started requiring a higher level of QC on mixtures with >25 analytes.

I can call the manager of that department and do some chewing out if you wish.

Just give them another call and tell them you need it immediately or they will lose a repeating sale.

Miraculously, those magic words can work wonders.

Good luck,
