A condensation nucleation light scattering detector (CNLSD) was adapted for use as a detector for supercritical fluid chromatography. The performance of the CNLSD was evaluated and compared to evaporative light-scattering detector (ELSD) using a well-defined equimass mixture of uniform poly(ethylene glycol) oligomers and a certified reference material of poly(ethylene glycol) 1000. The CNLSD was able to detect a 10 times less concentrated solution of uniform oligomers compared to the ELSD. The quantitativeness of CNLSD was high enough to obtain the molecular mass distribution of poly(ethylene glycol) 1000 without any calibrations; on the other hand, the original data measured by ELSD was about 4% smaller than the certified value of poly(ethylene glycol) 1000. The CNLSD was suitable for supercritical fluid chromatography as a mass concentration detector.
