The main instruments in the laboratory are:
The laboratory has compiled an in-house library containing 2,000 MSn spectra of plant small molecules and holds an academic reference collection of 1,250 natural products.
Access to the laboratory is generally through a grant-funded project with a Kew co-PI that aligns with Kew’s strategic aims, although we have the ability to perform a limited number of analyses as a chargeable service.
