@Cardin, Thank you. Bruker V70 is better because one can collect spectrum from UV to far IR in one run, without manual changing of the optic hardware. Moreover Bruker V70 offers higher scan rate which is good in chemical kinetics. Bruker V70 works better with photoacoustic accessory. And in my country has better technical support. The last one is the most important,. Good technical support helps in overcoming all problems with equipment by myself without draining the money. This the most important.
