The Optilab ® differential refractive index (dRI) detector may be used in conjunction with any HPLC, FPLC, GPC or FFF separation system, plus a Wyatt DAWN ® or miniDAWN ® multi-angle light scattering ...

ABSTRACT Recent advances have made ground‐based relative astrometry accurate to 100 microarcseconds (μas) or better a possibility. An important systematic effect on such measurements is the refraction ...

Light scattering methods are often called ‘'absolute’ because the addition of a light scattering detector to an SEC system enables direct molecular weight measurement without creating a calibration ...

ORLANDO, Fla. — Femtosecond laser anterior capsulotomy yielded more predictable refractive outcomes than manual capsulorrhexis methods, a surgeon said here. Capsulotomy technique and other factors ...
