The 6520 Q-TOF offers high performance in important categories, including attomole sensitivity; better than 2-ppm MS mass accuracy; better than 5-ppm MS-MS mass accuracy; tenfold improvement in in-spectra dynamic range without loss of sensitivity; mass resolution to 20,000; fast data acquisition ([greater than or equal to] = 10 MS-MS spectra/sec) compatible with fast LC chromatography; and broad mass range from m/z 25 to 20,000.

The technique is highly sensitive, meaning it can detect Coxiella burnetii strains at very low concentrations, specifically at the attomole level, which is equivalent to 1 X [10.
His thesis describes how electrodynamically levitated droplets can be used to create sample spots ~20 [micro]m in diameter and deposited with [+ or -] 5 [micro]m precision that provide routine detection of attomole quantities of peptides and proteins by MALDI-MS while consuming < 50 nL of solution.

We report here significant improvements to the assay that increases the sensitivity by two orders of magnitude, down to a single attomole of labeled target in a complex target mixture (for comparison, the detection limit of the Affymetrix microarray chip is about 15 amol per transcript).
