Robust and precise<br />
Do you want to analyze amino acids Do you have to<br />
comply with the test methods listed in the pharmacopoeias,<br />
e.g. USP (Method 1) By combining the<br />
886 Professional Thermostat / Reactor with the 887 Professional<br />
UV/VIS Detector you can work precisely and<br />
accurately in compliance with the standards.<br />

<strong>Amino</strong> acids (0.5 mM; 20 components). Column: Metrosep <strong>Amino</strong> <strong>Acid</strong>s 1 - 100/4.0, eluent:<br />
lithium citrate gradient similar to USP (Method 1), 0.4 mL/min, 60 °C, postcolumn<br />
reaction: ninhydrin reagent, 0.2 mL/min, 120 °C, wavelength 570 nm.<br />
For determination of amino acids in compliance with USP (Method 1), the 886 Professional<br />
Thermostat / Reactor ensures the required 120 °C for postcolumn derivatization.
