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'.

Not Finding What You Are Looking For?

In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.

Laser desorption/ionization time-of-flight mass spectrometry on sol-gel-derived 2,5-dihydroxybenzoic acid film.

Ya-Shiuan Lin et al.

Analytical chemistry, 74(22), 5793-5798 (2002-12-05)

This work presents a novel method for direct desorption/ ionization of analytes from sol-gel-derived film. 2,5-Dihydroxy benzoic acid (DHB), a common MALDI matrix, was incorporated into a sol-gel polymeric structure. The sol-gel-derived DHB thin film can assist the mass analysis

Improved liquid-chromatography of aspirin, salicylate, and salicyluric acid in plasma, with a modification for determining aspirin metabolites in urine.

J N Buskin et al.

Clinical chemistry, 28(5), 1200-1203 (1982-05-01)

Detailed performance specifications are given for a specific and sensitive liquid-chromatographic assay for aspirin, salicylic acid, and salicyluric acid in plasma. The sensitivity of this method for aspirin (50 micrograms/L) is 10-fold that of previous methods, so that concentrations of

Simultaneous liquid-chromatographic quantitation of salicylic acid, salicyluric acid, and gentisic acid in urine.

B E Cham et al.

Clinical chemistry, 26(1), 111-114 (1980-01-01)

We have developed a specific and sensitive method for the determination of salicylic acid, salicyluric acid, and gentisic acid in urine. Any proteins present are precipitated with methyl cyanide. After centrifugation, an aliquot of the supernate is directly injected into

Subventricular zone lipidomic architecture loss in Huntington's disease.

Ultra-Pure MALDI Matrices

One of the most important aspects of our ultra-pure MALDI matrix substances is their ability to dissolve rapidly and completely; a brief vortex mixing is typically sufficient.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
