A firearm includes a noise suppressor comprising ports in the barrel opening into an annulus provided between a barrel and a sleeve extending from adjacent the muzzle to adjacent the receiver. In the annulus are a series of baffles. The most upstream port opens upstream of the most upstream baffle and downstream ports open between adjacent baffles. In some embodiments, the upstream ports are considerably larger than the downstream ports. Propulsion gases escape from the barrel into the annulus before the projectile clears the muzzle. Sabot rounds or shotgun rounds can be safely fired in the weapon because the sabot carrier or shot cup don't begin to expand until it is past the muzzle end so it cannot damage the noise suppressor.

A shotgun metabolomics approach using MALDI-tandem mass spectrometry was developed for the rapid analysis of cellular metabolites. Through the use of neutral organic solvents to inactivate endogenous enzyme activities (i.e., methanol / chloroform / H2O extraction), multiplexed extraction conditions and combinatorial alterations in matrix stereoelectronic composition and analyte interactions, multiple suites of metabolites were directly ionized and quantitated directly from biologic extracts without the need for prior chromatographic separation. Through combinatorial alterations in 9-aminoacridine charge, aromaticity and stacking, a set of multiplexed conditions was developed that allowed identification of many hundreds of peaks corresponding to metabolites from mouse heart extracts. Identification of metabolite peaks was based on mass accuracy and isomeric species were assigned based on diagnostic fragment ions present during tandem mass spectrometry for many of the identified metabolite peaks.
