Restek, 31699, LC Performance Test Mix, Methanol, 1 mL/ampul

The National Institute of Standards and Technology (NIST) has formulated a mixture that is highly effective for characterizing LC columns for efficiency, void volume, methylene selectivity, retentiveness, and activity toward chelators and organic bases. Results can be used for column classification, for column selection, for monitoring column performance over time, or for quality control. We test our material against the NIST 870 standard. Amitriptyline hydrochloride (549-18-8), 2800 µg/mL Ethylbenzene (100-41-4), 1700 µg/mL Quinizarin (81-64-1), 94 µg/mL Toluene (108-88-3), 1400 µg/mL Uracil (66-22-8), 28 µg/mL
