Hi...it's me again, now I need a help about degradation of PCP using gamma rays. with parameters: pH, Spektrum and COD. Is there anybody who can help me?...
Yes True, Flame is fomed of matter! It is formed of the elements that were included in the oxydaoreduction reaction heated at acertain tempererature. It may be...

I'm searching for a simpler way to analyze for Acid Soluble Sulfate and Chloride in concrete and aggregate. We currently use the gravimetric method for both ...
What is the shortcoming with the method you are using? Gravimetric analyses are historically very precise (or can be). Is there some specific reason you WANT...
Time is the major problem. The sulfate gravimetric method is a long and tedious procedure. According to the sulfate method You need to wait for 4 hrs for the...
I am kind of stumped. I was looking for a direction for method development of a stability indicating method for multiple analytes of a pharmaceutical product ...
Hi <br><br>Look for these methods:<br><br>- ionic liquid chromatography<br>- sulfate and chloride specific electrodes<br><br>There also are volumetric methods....
Have you thought about HPLC analysis? <br>Using UV/visible detector, you could monitor for methylene blue with time.<br>You could also try to hydrolyse methyl ...
Please, help me if you know.<br>I wonder what kinds of signals are output signals (when they exit from a detector<br>and go into a computer). I mean various...
Output signals are very definately not standardized....the nature of each experiment in large part determines the signal. In fact, each company will handle ...
I'm sorry I've taken so long to reply to your post. The answer to your problem(s) could well be thermometric titration. We can do both sulphate and chloride ...
We have a certain amount of an acid which is dissolved in water. Can we predict pH of the obtained solution if we know the dissociation constant of the acid. ...
Ive just started my BSc in analytical chemistry and one of my first laboratory practicals was in NMR. The machine was an old 90MHz one.in the practical we used...
hello,sorry for delay,you can predict the pH of your solution as follow:<br><br>pH = 0.5(pKa + pC) where,<br><br>Ka = dissociation constant of the acid.<br>C =...
