We use strips that we buy from Fisher, EMD brand and others.  They come 
in various ranges.  They will detect MOST peroxy compounds and all 

There are a series of articles on peroxide formers and other time 
sensitive chemicals you may find useful.

I use the QuantoFix test strips, manufactured by Macherey-Nagel.  They 
work on 6 color ranges =E2=80=93 0, 1, 3, 10, 30 and 100 mg/L of 
peroxide as H2O2.

Macherey - Nagel has a broad line of test strips and test strips 
specifically for peroxides that I have used.  Good product.

I use the standard KI and starch method.  That works great, except for 
certain water soluble materials.  (THF and PEG ethers are examples.)  
For those items, you can just put the KI and starch solution on some 
filter paper, mostly dry it, and then add the material.  The reaction 
requires water, so don't overdry it.  If you don't want to fool around 
with making your own, you can buy the test strips from Sigma-Aldrich.
