Why is Chromatography <621> Important? Question From CURRENT USP -NF Online FAQs1 Q. How much can I modify a chromatographic procedure and still be in compliance? Can column length, internal diameter, mobile phase composition be modified? A. Chromatography <621> contains a list of allowed adjustments to chromatographic systems.The USP Approach for Selecting Columns of Equivalent chromatographic columns uspThe USP Database was developed by the USP Working Group on Column Equivalency using the NIST SRM 870. All data being displayed was generated by the column manufacturers after evaluation of the chromatographic phase. A review was published in Pharmacopeial Forum 31 (2), pp. 637645, 2005 (224KB).

tography useful in qualitative and quantitative analyses employed in USP procedures are column, gas (GC), paper, thin-layer (TLC) [including high-performance thin-layer chromatography (HPTLC)], and pressurized liquid chromatography [commonly called high-pressure or high-performance liquid chromatography (HPLC)]. GENERAL PROCEDURESPQRI Approach for Selecting Columns of Equivalent chromatographic columns usp - USPUSP's PQRI Approach to Selecting Columns of Equivalent Selectivity was developed over a 10-year period from 1998 to the present time.

Minimum Sample Weights According to USP . 41>, OIML R76 and EURAMET cg-18 The smaller the weight of the sample, the larger the relative measurement uncertainty that the weighing is subject to. There are various concepts for specifying corresponding minimum sample weights so as not to exceed a specified relative measurement uncertainty.L8 - HPLC Columns, by USP Code | Sigma-Aldrich17 rows · USP L8 HPLC Columns An essentially monomolecular layer of aminopropylsilane chemically 58338SUPELCOSIL LC-NH2 HPLC Column5 m25 cm × 4.6 mmK08670343Kromasil® NH2 HPLC Column5 m250 mm × 4.6 mm1.50844LiChrospher® 100 NH2 (10 µm) LiChroCART 2510 m-1.50244Purospher STAR NH2 (5 µm) LiChroCART 125-45 m-See all 17 rows on www.sigmaaldrich chromatographic columns uspL1 - HPLC Columns, by USP Code | Sigma-AldrichUSP L1 HPLC Columns Octadecyl silane chemically bonded to porous silica or ceramic micro-particles, 1.5 to 10 m in diameter, or a monolithic rod.
