In the profile data type, you can see the shape of the peaks in the mass spectrum. Each atomic
mass unit is divided into many sampling intervals. The intensity of the ion current is
determined at each of the sampling intervals. The profile data type displays the intensity at
each sampling interval with the intensities connected by a continuous line. In general, use the
profile scan data type when you tune and calibrate the mass spectrometer so that you can
easily see and measure mass resolution.
The centroid data type displays the mass spectrum as a bar graph and sums the intensities of
each set of multiple sampling intervals. This sum is displayed versus the integral center of
mass of the sampling intervals. In general, use the centroid scan data type for data acquisition
for faster scan speed. Data processing is also much faster for centroid data.
The TSQ mass spectrometer can operate in a mass/charge range of 10 to 3000 Da (TSQ
Quantum™ Access™, TSQ Quantum Access MAX™, TSQ Vantage EMR™, and TSQ
Quantum Ultra EMR™ mass spectrometers), or 10 to 1500 Da (TSQ Vantage™, TSQ
Vantage AM™, TSQ Quantum Ultra™ and TSQ Quantum Ultra AM™ mass spectrometers).
