Frequently Asked Questions

Q: Are there expiration dates for your columns and standards?

A: There is no specific expiration date on our columns and standards. However, we suggest the following shelf lives below. This is helpful for our customers that may purchase several columns/standards to store in advance of future usage.

  1. Analytical columns: 2 years from purchase date
  2. Guard columns (pre-columns): 3 years from purchase date
  3. Standards: 3 years from purchase date

Q: Can I return my column if it does not perform to my standards?

A: Unfortunately, we cannot accept returns. We have a 10-day limited warranty. You may return the column if you can show proof that the column is defective within 10-days. Each column is shipped with a Certificate of Analysis. The best way to determine a defect is to run the standard provided on the certificate.

Q: Can you compare your column with the competitors’ columns?

A: We do not name the competitor out respect for their brand. However, in most cases, one can easily determine who the competitor is, especially for experienced chromatographers. We do provide a column equivalency chart in Customer Support.

Q: Can you develop an application for me?

A: All applications are developed in Japan. Applications are not developed by individual request unless there is a large demand. Before inquiring about a specific application please search for existing methods on our website. There are hundreds of methods available.

Q: Do you offer UHPLC (UPLC) columns?

A: Currently we do not offer these columns for all common applications. There are two non-porous ion exchange columns that we do offer: PIKESS DEAE-2B (anion) and PIKESS SP-2B (cation) that can withstand UHPLC pressures.
