Question 1

What are Sumichiral® chiral columns used for?

Accepted Answer

Sumichiral® chiral columns are used to separate enantiomers in chiral compounds for analytical and preparative HPLC. They help determine enantiomeric purity, develop chiral methods, and support QC and R&D workflows.

Question 2

Which Sumichiral column should I choose for my compound?

Accepted Answer

Start by checking the compound database on this page (Group A–J) to see the representative column used for similar functional groups. If your compound is not listed, share its structure, pKa, and solvent compatibility, and we can recommend a starting screen.

Question 3

Do Sumichiral columns support analytical and preparative HPLC?

Accepted Answer

Yes. Sumichiral columns are widely used for analytical method development and can also be used for preparative separations depending on column dimensions, loading, and solvent system.

Question 4

What mobile phases are typically used with Sumichiral chiral columns?

Accepted Answer

Typical mobile phases depend on the stationary phase and analyte properties. Common approaches include normal‑phase (e.g., hexane/alcohol modifiers) and reversed‑phase (water/ACN or MeOH buffers) where compatible. Always confirm solvent compatibility for the selected column series.

Question 5

How do I condition a new chiral column before first use?

Accepted Answer

Flush with a compatible solvent system at low flow rate to remove shipping solvent and equilibrate to your working mobile phase. Use gradual solvent transitions (avoid sudden changes in strong solvents) and follow recommended pressure limits.

Question 6

How should I store Sumichiral columns?

Accepted Answer

Store the column in a compatible storage solvent recommended for the series (often the same as a stable mobile phase composition). Seal end‑fittings tightly to prevent drying and keep at room temperature away from vibration and direct sunlight.

Question 7

What are common reasons for high backpressure or peak broadening?

Accepted Answer

High backpressure can occur due to blocked inlet frits, particulate contamination, or incompatible solvent mixing. Peak broadening can result from inadequate equilibration, extra‑column volume, strong injection solvent, or column aging. Using an inline filter and clean solvents reduces risk.

Question 8

Can I use buffers and salts with these columns?

Accepted Answer

Buffer/salt compatibility depends on the specific Sumichiral stationary phase and operating mode. If using buffers, ensure the column is designed for aqueous operation and avoid precipitation (especially with high organic content).

Question 9

Do you provide method development support in India?

Accepted Answer

Yes. Akira Analytical Solutions Pvt. Ltd. can support selection, method screening, and application guidance based on your compound class, detection, and instrument configuration.

Question 10

How can I order and what information should I share for a quotation?

Accepted Answer

Share the column code/series (e.g., OA‑xxxx), dimensions, particle size if applicable, and quantity. If you need selection help, share compound name/structure, sample solvent, and target purity so we can recommend the best starting options.
