The NMR system that produced all the spectra on this page costs less than $40,000. 31
NMR can be used to analyzepesticides and other phosphorus- containing chemicals such as trimethylphosphite (spectrum shown).

H NMR analysis of acetyl acetone at -19°C, +40°C, and+100° C shows the temperature dependence of this keto/enol equilibrium.
The multi-nucleus, easy-to-use, under-$40,000, T-60 NMR spectrometer system. You get back a lot more thanyouput in.
