Could it be that the IPA you are using in the solvent/DI mix is not anhydrous, or in some other way not the correct purity? If it is not correct you will not be able to calibrate. Best rgds, Peter B.

The industry standard for Resistivity of Solvent Extract (ROSE) Testing analysis is IPC-TM-650 Method 2.3.25 – Detection and Measurement of Ionizable Surface Contaminants by Resistivity of Solvent Extract (ROSE).

A fairly painless method for monitoring cleanliness is Resistivity Of Solvent Extract [ROSE]. Equipment is: * Omegameter * Ionograph * Ion Chaser [Zero-Ion] Anyone who desires to use an Resistivity Of Solvent Extract tester should read EMPF repor

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days

This is a (Resistivity of Solvent Extract (ROSE) tester. Per IPC standards, ROSE testers use a test solution comprised of 75% IPA (99% pure) and 25% DI water. -Mike Konrad Aqueous Technologies www.aqueoustech.com konrad@aqueoustech.com

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

While J-STD-001 specifies an upper limit for acceptance of assembly, we use Resistivity Of Solvent Extract testing as a process control. In truth, this "LT 10.07 �gm/sg in NaCl equivalent" measurement has substantial limitations, not the least of wh

Bare board cleanliness is still primarily measured by resistivity of solvent extract (ROSE) using instruments such as Omegameters and Zero Ions. What is considered as "acceptable" cleanliness varies between specification and from company to company.

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

Ionic cleanliness is pretty much meaningless, when discussing nc flux residues. If you do the good solder routine and measure the boards, you'll be in the out-house, because the water in your resistivity of solvent extract tester will turn the res o
