Thank you for choosing Shinwa Chemical Industries’ products.

Due to drastic decreases in supplies of diatomaceous earth gas chromatography supports and Chromosorb Century series supports from our supplier, we have been forced to discontinue sales of a number of our products.

Although we are continuing to try to secure stable supplies of these items, our supply situation remains unchanged.

Please refer to the link below for details regarding the supports, packing materials, and packed columns we currently supply.

In order to alleviate this situation, we have developed a new silica support called Shinwasorb, which surpasses diatomaceous earth supports in performance. This new support was officially released last year.

As Shinwa Chemical Industries is capable of supplying this new gas chromatography support on a stable basis, please consider the possibility of employing this new product as a replacement for existing products.
