| USP Code | USP Packing Description | SUMICHIRAL Column / Relevant Phase | Notes for Customers |
|---|---|---|---|
| L36 | A 3,5-dinitrobenzoyl derivative of L-phenylglycine covalently bonded to 5 µm aminopropyl silica. | SUMICHIRAL OA-2000 | Relevant where the method calls for an L36 type chiral stationary phase. Confirm column dimension, mobile phase and system suitability before substitution. |
| L72 | (S)-phenylglycine and 3,5-dinitroaniline urea linkage covalently bonded to silica. | SUMICHIRAL OA-3300 / OA-3300S | Relevant for phenylglycine-based urea type chiral selectivity. Useful reference for monographs or methods requiring L72 packing chemistry. |
| L127 | Crown ether chemically bonded to 5 µm silica gel substrate; active site is (S)-pseudo-18-crown-6-ether. | SUMICHIRAL OA-8000 | Relevant for crown ether type chiral separations, especially amino compounds where the method specifies L127 type packing. |
Only SUMICHIRAL-relevant USP listings are shown here. For strict compendial work, share the complete USP method, target analyte, column dimension and system suitability limits before substitution or ordering.
Frequently Asked Questions
Does every USP L-code apply to SUMICHIRAL?
No. Only USP codes where SUMICHIRAL columns are specifically relevant are listed on this page. Achiral L-codes and unrelated packings are intentionally removed.
Which SUMICHIRAL column is relevant to USP L36?
SUMICHIRAL OA-2000 is relevant to L36 type chiral stationary phase chemistry.
Which SUMICHIRAL column is relevant to USP L72?
SUMICHIRAL OA-3300 and OA-3300S are relevant to L72 type phenylglycine and 3,5-dinitroaniline urea linkage chemistry.
Which SUMICHIRAL column is relevant to USP L127?
SUMICHIRAL OA-8000 is relevant to L127 crown ether type chiral stationary phase chemistry.
Can I replace a USP column with a SUMICHIRAL phase?
Only when the packing chemistry, column dimensions and performance meet the monograph and system suitability requirements. Submit the method details for guidance before ordering.
