This resource consists of methods for matrix-assisted laser desorption ionization (MALDI) mass spectrometry on a wide variety of synthetic polymers. The methods are taken from the peer-review scientific literature. The database covers the period from 1988, the year of Tanaka's first paper on the subject, through 2011. Each recipe comes with a literature citation and associated digital object identifier (DOI) when available. The database currently contains entries for over 1250 polymer/matrix combinations.

This database is the product of a multi-year, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library.

Liquid-chromatography-mass spectrometry (LC-MS) raw data sets from various instruments delivered in their native instrument format. 31 files in all. 7.5 GB data.

Sulfonephthalein pH indicator dyes have historically been noted for impurities originating from the synthesis process which lead to batch to batch differences in pH measurements. Uncertainties up to 0.1 pH units have been attributed to impurities in these reagents.
