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?

What flow rate should I use with Ascentis® Express HPLC Columns?
Based on the minimum in the van Deemter curves, higher flows than 5um particle columns are required in order to maximize Ascentis Express column efficiency. The suggested starting point for flow rate for Ascentis Express columns: 1.6 mL/min for 4.6 mm ID; 0.8 mL/min for 3.0 mm ID; and 0.4mL/min for 2.1 mm ID.
Can Ascentis® Express HPLC Columns be used for LC-MS?
Express Fused-Core™ particles were designed with LC-MS in mind. Even extremely short column lengths exhibit sufficient plate counts to show high resolving power. The flat van Deemter plots permit resolution to be maintained at very high flow rates to maximize sample throughput. All Ascentis stationary phases have been evaluated for MS compatibility during their development, and the Express phases are no exception. You can expect extremely low column bleed and background while maintaining longest possible column lifetime. A bonus of Ascentis Express columns for high throughput UHPLC and LC-MS is that they are extremely rugged and highly resistant to plugging, a very common failure mode for competitor columns.

Articles
Phosphonates are a class of compounds commonly used for therapeutic applications of antiviral drugs. These compounds can be difficult to analyze due to their highly polar nature and lack of UV active chromophores.
Protocols
Reversed-phase HPLC sometimes requires ion pairing for adequate retention of polar compounds due to hydrophobic interactions.
