How to Find a Lot/Batch Number for COA

Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

Aldrich Products

For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.

Delphine Debois et al.

Analytical chemistry, 82(10), 4036-4045 (2010-04-20)

Matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS) imaging is a powerful technique giving access to the distribution of a large range of biomolecules directly from a tissue section, allowing, for example, the discovery of new pathological biomarkers. Nevertheless, one main difficulty

Mass spectrometric characterization of phosphorylated peptides using MALDI in-source decay via redox reactions.

Matrix-assisted laser desorption/ionization in-source decay (MALDI-ISD) has been used for characterization of a phosphorylated peptides and proteins because labile phosphate group is not lost during the MALDI-ISD process. The conventional MALDI-ISD is initiated by the hydrogen transfer from reducing matrix
