Development of this specification primarily with reference to GB/T 6041-2002 "General mass spectrometry", JJF 1164-2006 "Desktop gas chromatography - mass spectrometry calibration specifications" and other norms. This specification is the first release. Flight mass spectrometer calibration specification1 ScopeThis instruction applies to electrospray ionization - time of flight mass spectrometry and matrix-assisted laser-induced desorption time of flight mass spectrometer Calibrate other types of flight mass spectrometer can be calibrated with reference to the present specification. 2. References This specification refers to the following documents. JJF 1164-2006 Desktop gas chromatography - mass spectrometry calibration specification GB/T 6041-2002 General Mass Spectrometry Laboratory use specifications and test methods GB/T 6682-2008 Analysis For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.3 terminology and units of measurement3.1 Terms 3.1.1 Sensitivity sensitivity [GB/T 6041-20022.2} Under specified conditions, the response to the value of a mass peak, the instrument unit generated by the sample. 3.1.2 The ability to distinguish resolution In a given sample conditions, instrument two adjacent mass peaks discriminatory power. Two adjacent high-mass spectrometry When the peak, the peak is not more than 10% of the peak height, it is defined as can be distinguished. Note. The ability to distinguish two peaks of representation when R peak at 10% peak height, the quality of the two peaks represented by the average value of quality The ratio of the amount of the difference. When describing the use of mass spectral peak mass to charge ratio, listed in the corresponding resolution of the data is appropriate, because different instrument Device, while its resolving power varies with different mass to charge ratio. 3.1.3 SNR signaltonoiseratio [GB/T 6041-20022.9} In mass spectrometry, the signal strength and noise intensity ratio. 3.2 units of measurement 3.2.1 atomic mass units (u) atomicmassunit] [JJF 1164-20063.64 OverviewFlight mass spectrometer is a class of ion flight tube as a mass spectrometer detector, ionization generated ions Pulsed electric field accelerated into the field-free flight tube, and at a constant speed toward the ion receiver. The larger the ion mass, to The longer the time of the receiver is used; the smaller the ion mass, reach the receiver used the shorter the time, according to this principle can be In the mass of ions of different mass to charge ratio of the size of the separation. Flight mass spectrometer according to the ionization of different ways, Can be divided into electrospray ionization time of flight mass spectrometer (electrosprayionization-time-of-flight-massspectrome- ter, ESI-TOF-MS), matrix assisted laser-induced desorption time of flight mass spectrometer (matrix-assistedlaserde- ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1528-2015_English be delivered?Answer: Upon your order, we will start to translate JJF 1528-2015_English as soon as possible, and keep you informed of the progress.
