Wakopak® Handy ODS is an ODS column provided with excellent cost performance and designed for ease of use. It is low-priced but has sufficient performance for high-level analysis. The column comes with a certificate for supporting validation of analytical procedures to provide complete support for the column. The packing of the column is simplified in consideration of global environment.

1. Sufficient performance for high-level analysis
4.6 mm × 150 mm … N = 12,000 or more
4.6 mm × 250 mm … N = 20,000 or more
2. The column contains high-purity silica gel and is suitable for separation of metal coordination compounds.
3. It is end-capped and suitable for separation of basic compounds.
4. It is a monomeric ODS showing general retention capacity and suitable for wide-range analysis.
5. The column life is improved because the column pressure is low.
6. Priced as low as pre-columns
7. Reliable support for column
(1) Validation of analytical procedures in conformity
with GLP and GMP is supported.
* Support data is supplied with the column.
* 3 lots of filler are supplied constantly.
(2) Quick delivery
