Thank you for the info. i have not researched that particular method. I did some quick digging, it appears it is way out of my price range for equipment, although does seem to be a great fit. I guess that's why i keep coming back to uv/vis spectrophotometer (the price). So circling back, any...

Hello, i have a need to identify unknown substances. I've been researching spectroscopy and and the various methods. I've read all about the different types and uses and I've settled on a uv/vis spectrophotometer as the instrument. i know its not 100% used for qualitative analysis but its good...

actually, yes the capacitor is several years old, maybe decades, its old military surplus that have been shelved for years. so what I am gathering is stick to what doesn't blow it and slowly rasie the voltage over a fwe days? leave it on non-stop? that kinda scares me leaving it unattended that...

it is a tube amplifier. i don't have many details about it, its very old and i got it off ebay. i believe it is diode bridge rectified, althought I am not 100% positive.it is powered via 120v wall outlet. I am not sure if your familiar with the ssy1 nd:yag laser but I am powering the Pulse...

no, i don't have a scope. but something you said makes sense. is it possible that in my particular setup that 700v is = 950v? so when i set higher than 700v on my power supply, due to components, that its blowing it due to over voltage? that seems to be a very reasonable answer. also, I've never...

sure, beside the obvious LOUD pop noise, balls of blue/white light appear on the negative cable of the capacitor and appear to arc to the casing. its a capacitor surrounded in a gel, that's in a an aluminum enclosure. the wire eventually gets burned and burn marks are on the aluminum enclosure...

i am positive the polarity is correct, it is made here in the USA and i checked the voltage by using my multimeter at the capacitor. i know the ESR is 0.02 Ohm, but honestly that's about it. I am not familiar with how your getting the 950v is 700v with the 33% overshoot. i understand the basics...

Hello, i have a situation that i do not completely understand. i have a capacitor, 35uF @ 950V. i have a regulated DC power supply connecting to it. when i set the voltage to anything above 700V the capacitor pops and sparks. when its below 700, it seems just fine. i was told via forums from the...
