Oslo University Hospital invites tenderers to a competition for the procurement of 1 UHPLC-MS/MS system for quantitative analyses of Metanephrine, Normetanephrine, Methoxyflurane and Estradiol. All additional components that are necessary for the analysis equipment to be operative must be included in the procurement. The estimated sample volume is approx. 25,000 per annum. The tender shall also include an option price for an additional LC-MS/MS system for analysing other hormones. The equipment shall be used for monitoring medicine levels in patients and it must, therefore, be able to be used for analyses with very good operational stability, selectivity, sensitivity, precision and linearity.
