nanoEA

δ13C δ15N

nanoEA is a custom iRMS peripheral developed at UCSC SiL according to the design of Pollisar et al., 2009. The nanoEA cryofocussing design allows for high-yield, high-precision measurement of C and N stable isotope ratios in very small samples such as mesoscopic organisms or HPLC extracts. The iRMS analysis of compound specific isolates via nanoEA bypasses the necessity for derivitization which can limit practical application or accuracy of isotope ratio measurements made via GC-C-iRMS analysis. The nanoEA sample measurement rate is $13.00 for UC and affiliates or $20.02 for non-affiliates.
