During Soundness testing of Cement by Lechatelier method
the Cement mould expands about 20 mm when merged in curing
water for 24 hours after mould preparation.In that Cement
MgO content is about 3.0%,SO3 is about 2.6% & Blaine is
about 360 M2/Kg.Guess the reason & suggest solution.
What is the exact reason to use THF and IPA in buffers of
Reverse phase HPLC as a solvent?
graphaite has higher melting point than fularine
How many moles of sodium hydrogen phosphate can be prepared
from 3 mol of sodium hydroxide and phosphoric acid?
Why we use potassium dichromate in control of absorbance in uv
region and copper sulphate in control of absorbance in visible
NIR wave length range how much
How can we calculate "confidence interval" in analytical method validation? Pl. explain with example.
As per ICH related substances stability trend limit from
initial to shelf life
In testing of Cement the formula for water requirement for
setting time is as below-
Water required for setting time = NC x 0.85
The question is that what is the logic of 0.85 in this
which effect is mainly responsible for chromatographic separation when silica is the statinary phase at TLC?
thanks in advance
