It has come to our attention that counterfeit versions of our ULTRON ES-OVM HPLC column series are being distributed in the Chinese market. Some of these counterfeit products are highly sophisticated and may be difficult to distinguish from genuine ones.

To safeguard the quality and reliability of your analytical results, we urge all customers and distributors to take the following precautions.

**Risks of Using Counterfeit Products**

- **No Quality Assurance:** Counterfeit columns may not deliver the expected separation performance and durability provided by genuine ULTRON products.  

- **Data Reliability Issues:** Use of counterfeit columns can lead to the introduction of impurities, compromised analytical results, and a shortened column lifespan.

**Verification Guidelines**

- **Check the Product Serial Number:** Always confirm that the product's serial number matches the one issued by our company. This is a critical step in verifying authenticity.  

- **Inspect the Packaging and Column Box:** Genuine ULTRON ES-OVM products are packaged in a specifically designed box with consistent coloring, branding, and labeling. Please verify that the outer packaging and column box match the original design specifications. Any irregularities in color tone, print quality, or labeling layout may indicate a counterfeit product.

**Contact Information**

If you suspect that a product may be counterfeit or if you wish to verify the authenticity of a ULTRON ES-OVM column, please contact us directly.

We remain committed to maintaining the highest standards of product quality and customer trust. Thank you for your attention and cooperation.
