The phrase "assignment of mass" is correct and usable in written English.
It can be used in scientific or academic contexts, particularly in physics or chemistry, to refer to the process of determining or allocating mass to an object or system.
Example: "The assignment of mass to the particles in the simulation was crucial for accurate results."
Alternatives: "mass allocation" or "mass designation".
This may have led to the assignment of the mass loss at 300°C to 420°C to the PSt template in several reports [28 30].
In all cases the assignment of the mass spectra to the database entries is unequivocal.
Non-targeted metabolome analysis was achieved by molecular mass assignment of high-resolution mass spectra obtained using a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer (FT-ICR-MS, APEX Qe, Bruker, Bremen, Germany) equipped with a 12-Tesla superconducting magnet and an Apollo II electrospray (ESI) source.
Although TOF MS is commonly used in MSI, FTICR MS is preferred due to its superior mass resolution and mass accuracy, which allows unambiguous peak recognition and precise assignment of exact masses.
For that set of assignments, the distribution of mass and isotopomer abundance errors are displayed in Figure 5B.
Purification, characterization, and analytical mass assignment of iNOS from DLD-1-5B2 cells are in progress to provide mass standardization for the iNOS immunoassay.
(Refer to Tables S1 S5 in the Supporting Information for the tabulations of mass assignments of fragment ions and abundances used for the calculations).
MSI with C60-SIMS allows mass-based discrimination of multiple specific quinolone species having subtly differing distributions, as well as confirmation of mass assignments with in situ MS/MS experiments.
Aromatic compounds identified in the pyrograms are presented in Table 1 with peak assignments based on comparison of mass spectra with the reference library as well as comparison with the literature [ 39].
Here, we describe how intrinsic features of antibody primary structure, most notably the interspersed segments of variable and conserved amino acid sequences, generate recurring patterns in the corresponding peptide mass spectra of V gene peptides, greatly complicating the assignment of correct sequences to mass spectral data.
