Chromatography Forum

We have a question about the different options to use gas filters for a ECD detector.

We use nitrogen as carrier and make up gas, and we would like to replace our actual filter. Nowadays we have a combined filter to remove oxigen, moisture and hidrocarbon (agilent filter), and we would like to replace it with filters that present indicator of color, because we want to control the quality of our gas supplier.

Does anyone help me and say what is the best option in the market for these types of gas filters?
What are the main advantages/disadvantages?

Best Regards

I believe that all of the reputable chromatography vendors provide quality filters so I would choose the filters from the vendor that can provide you the best service.

Hi!
Supelco have a heated trap...it's the best for ECD....http://www.sigmaaldrich.com/analytical- ... =110579091

You install this heated trap with a OMI indicator at the exit of this trap http://www.sigmaaldrich.com/analytical- ... e=14540530

After, you place a hydrocarbon trap.
