Regis Technologies Inc Ion Pairing Reagents and Buffers, Regis, ION PAIR CONCENTRATE Q12 (100 mL)
Q-Series Ion Pair Concentrates (For Anions) are Regis Quaternary Amines, Bulk Ion Pair Reagents (for Anions). The Q-Series is comprised of quaternary alkyltriethylamines that can be used for the resolution of negatively charged species. This unique set of cationic reagents was developed to complement the Sulfonate Series (S-Series) and is exclusively manufactured by Regis. The Quaternary Alkyltriethylamines are available as premixed 0.5 M solutions of alkyl amines. When diluted to 1 L with HPLC-grade water, a 10 mL bottle forms a 0.005 M buffered solution.
Regis Technologies Inc Hexyltriethylammonium Phosphate Buffer, 100ml
The Q-Series is comprised of quaternary alkyltriethylamines that can be used for the resolution of negatively charged species. The Q-Series Ion Pair Concentrates are available as premixed 0.5 M solutions of varying alkyl chain lengths. When 10 mL of concentrate is diluted to 1 L with HPLC-grade water, a 0.005 M buffered solution is formed.
