In protein mass spectrometry, tandem mass spectrometry (also known as MS/MS or MS 2) experiments are used for protein/peptide identification. A separate exhaust for the Ion source gas (nitrogen) must be provided to the atmosphere external to the laboratory clear from any air intakes for air conditioning systems.Further information: protein mass spectrometry The rotarg pump exhaust outlets must be vented to the atmosphere external to the laboratory clear from any air intakes for air conditioning systems. This should be regulated up to 3.5 bar (50 psi). This should be regulated at a supply pressure of 7 bar (100 psi).įor CID experiments a supply of clean, dry Argon is required. The instrument requires a clean, dry supply of nitrogen for source operation. This should be clean, dry and regulated at between 2 and 5 bar. The instrument requires a supply of compressed air for correct operation of the vacuum system. The instrument requires a chilled water connection to provide turbo pump cooling. They do not include the rotary pumps or the computer system. The following parameters are for the instrument main bench only. The relative humidity should not exceed 70%. The hegt dissipated into the laboratory from the instrument and pumps is about 2 kW. It is recommended that the instrument be sited in an air-conditioned laboratory, in a draught-free position and away from excessive amounts of dust. Short-term (1.5 hours) variations should be no more than 2☌. Optimum operating temperature lies in the range 19° - 22☌. The maximum ambient laboratory temperature should not exceed 30☌. The mass spectrum, either from a quadrupole experiment or from a TOF experiment is typically a record of the original sample's composition describing both the molecular weights and relative abundance of the components. They are then detected wich a microchannel plate detector and Ion counting system and this Output is then recorded as a mass spectrum Those ions pushed out of the OA describe either a V or W path travelling through the reflectron lens at the end of the Instrument. Tuning of the instrument can be established and elementarg mass spectra can be recorded. A collision cell is situated after the quadrupole to induce fragmentation from the MS/MS experiments.īeyond the quadrupole collision cell assembly is an orthogonal acceleration cell (OA) in which the Ions are either pushed downward into the TOF analyser or allowed to drift onward into the post acceleration photomultiplier detector (Dynolite(tm)). The quadrupole is operated as an Ion transport element for MS experiments and as a mass selection device for MS/MS experiments. The Q-Tof Ultima API utilises a high perfonnance, research grade quadrupole mass analyser and orthogonal acceleration time of flight (TOF) mass spectrometer. Different experiments can be performed applicable to the Sample type and Information required. This configuration permits both interactive and fully automaue control of the System.

The user controls the instrument from a PC using MassLynx Software. The instrument is for research use only and is not intended for use in diagnostic procedures. It can provide molecular weight determination, molecular structure Information and quantitative analysis of the Samples introduced. The Q-Tof Ultima API is a hybrid quadrupole time of flight mass spectrometer. Please refer to the text of the offer for the exact scope of delivery. They do not represent the scope of delivery.
