問題

某客戶找到用Bio-Rad Aminex HPX-87H column 分析衣康酸的以下條件，請問Concise Coregel 87H3可以取代Aminex HPX-87H ？

使用條件

Mobile phase: 0.5mM H2SO4

Flow rate: 0.6 ml/min

Temp: 50 C

回應

Concise原廠回應：我們的Coregel 87H3略好於Aminex HPX-87H，因此如果客戶已經在HPX-87H上進行了這種類型的分析，那麼我們的87H3應該也能正常分析。

如果有更進一步關於樣品混合物（衣康酸和其他成分）的一些細節，我們可能會建議一個更好的替代品。

Could Coregel 87H3 replace Aminex HPX-87H for this analysis? or, do you have orther suggestion?

Condition

Mobile phase: 0.5mM H2SO4

Flow rate: 0.6 ml/min

Temp: 50 C (she hope the temperature would not be too high)

Answer

Our 87H3 is slightly better than the Aminex HPX-87H, so if the customer already performed this type of analysis on the HPX-87H then our 87H3 should work as well (see attached c-gram).

If we have some details about the sample mixture (Itaconic acid and what other components), we might be able to suggest a better alternative.
