Laboratory for mass spectrometry at NMBU/KBM
Our laboratory for mass spectrometry has existed since 1990 when we were the only laboratory on Campus with a mass spectrometer. At the time we had a double-focusing sector instrument from Jeol. Today we have several different mass spectrometers. Among other things, we have a state-of-the-art GC-Orbitrap, which is a high-resolution mass spectrometer. This instrument is very well suited for identification and quantification of a number of bioorganic or organic compounds, for example in foodstuffs, nature, the environment or elsewhere.

Orders and prices
The prices varies depending on the complexity of the samples and the necessary of sample preparation. It may also depend on separate agreements. See below for further details or contact the tenant responsible at the chemistry group.
Services
The laboratory for mass spectrometry is available for all relevant assignments, both mural and extramural. Students and scientists within the research group have priority. Others are encouraged to contact the rental site manager and the lab manager.
The type of analysis that we can offer today is GCMS analysis of fatty acid methyl esters (FAME). For this we use a 60 m long capillary column of the type Rtx-2330 from Restek. We have prices per sample where blanks are defined as normal samples. If you wish to carry out an injection with only solvent, the customer will not be charged for this. We strongly prefer that the samples are fully prepared in advance, i.e. that they are derivatized and found in the form of FAMEs. If you need to carry out sample preparation at KBM, laboratories can be rented, see the booking platform for the rental location at NMBU. If there is a need for something to be derivatized with us, this must be agreed in advance and then it will be an hourly price. If you want to run a standard row of FAME, we have this and you are charged for this as if it were a normal test.
Other analyzes than fatty acid analyzes can be carried out if the analyte and your sample are suitable for the column that we use on a daily basis. This could be relevant if the number of analytes is relatively few and you want identification and not quantification
Our LCMS instrument does not have any specific methods used for routine analyses. In recent years, the instrument has been used primarily for the analysis of monolignols, where we have developed a DI-ESI-MSMS method. We strongly recommend that the customer has his own method and brings along a riktog column and that analysis conditions are discussed before making an agreement. It is very important that solvents and mobile phase eom are compatible with LCMS and the same applies to the samples, they must not contain small amounts of substances that can clog or otherwise damage the instrument.
Order and price
Orders can eventually be placed via: https://ppms.eu/nmbu. Only a few instruments have been entered here so far, but it will be continuously updated. The prices are not legally binding and may vary depending on any agreements and regulations established by the faculty or university.

Assistance from an engineer or scientific personnel is available for an additional fee of NOK 1800 and NOK 1000 per hour, respectively. Assitance from scientific personnel implies an expectation of co-authprship on publications.
Research
The laboratory is active in a number of different projects with an emphasis on organic analytical chemistry, but reaction mechanisms and spectrum interpretation are also important topics.
