Sampling Rate

Question

Could someone clarify sampling rate units? I've seen it reported as "points/sec" How does this translate to hertz/sec? If someone can answer that would be great, if you can provide me with a source it would be fantastic

This should help. This is specific to GC but for the most part can relate to other instruments detectors.

Hi ecarenzo, As the information that james_jenkins has posted suggested, the sampling rate can be specified as Hertz (abbreviated Hz) or samples per second. These are two different terms for the same thing, so there is no conversion factor between the two. (OK, you could say the conversion factor between the two is 1, but that's like saying the conversion factor between kilometers per hour and kph is 1.) Saying "hertz/sec" is just wrong, unless the specification indicates the rate at which the sampling rate is changing per second. You may find it useful to refer to the Wikipedia article about Hertz. Start at http://wikipedia.org and type "Hertz" in the search area.
