Test means, test device and method for determining the ionic strength or specific gravity of a liquid sample |
摘要 |
A test means for determining the ionic strength or specific gravity of an aqueous test sample, the test means comprising a weakly acidic or weakly basic polyelectrolyte which is at least partially neutralized, and an indicator means capable of producing a detectable response to ion exchange between the polyelectrolyte and the sample. The test device comprises a carrier matrix incorporated with the test means, and the method for its use comprises contacting an aqueous test sample with the device and observing a detectable response.
