USP L43 PFP Column Classification for Method Evaluation
Browse active catalog products recorded with the USP L43 pentafluorophenyl (PFP) stationary-phase classification and compare exact specifications for method evaluation.
L43 is used for pentafluorophenyl (PFP) stationary-phase classification. It gives laboratories a direct route to catalog products recorded with this classification when reviewing an alternative selectivity option. The L-code does not establish that a product will reproduce another product’s separation; the exact phase, dimensions, operating conditions, and system-suitability evidence must be reviewed.
Selection Considerations
- Use L43 to identify candidate products, then confirm the exact PFP chemistry and manufacturer documentation for each part number.
- Compare particle size, pore size, internal diameter, length, and documented operating limits with the current method.
- Treat a stationary-phase change as a method-evaluation activity and verify system suitability under the intended conditions.

USP L-codes identify stationary-phase classifications. They do not establish product certification, approval, endorsement, or automatic method replacement.
Frequently Asked Questions
What does USP L43 describe?
L43 is the USP stationary-phase classification used for pentafluorophenyl (PFP) chemistry. It supports catalog discovery and is not a certification or replacement claim.
Can a PFP product be substituted for a C18 product without method work?
No. A stationary-phase change can alter retention and selectivity. Evaluate the exact product under the actual method conditions and acceptance criteria.
Why use the L43 page?
The page provides a focused route to active catalog products recorded with L43, then directs the user to compare exact product specifications before requesting a quote or beginning method work.
