Nicotine standard for validation of a GC-MS method

[mekibib1]

Hi there everyone, I work for an electronics cigarettes liquid manufacturer company. We are trying to validate our Nicotine analysis GC-MS method using reference materials.
We have been unable to find a Nicotine at 40 mg/mL here in the UK, We found a supplier for pure Nicotine (99.7%) but that entails working with a very potent concentration.
Does anyone know a reputable supplier at the above concentration range??

I would suggest talking to Chemservice here in the US. They make standards, they make custom compounds for that matter and I have found them very reasonable to work with. It would be a custom mix but probably well worth it.

Best regards,
