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 ...

In this month's edition of the LCGC Blog, discover how weighted least squares regression enhances quantitation accuracy in analytical chemistry, particularly for low-concentration analytes in HPLC.

A calibration curve has been created in accordance with ASTM D4929 method to show the analysis of chlorine (Cl) in oil. The only difference in method was the use of a rhodium anode tube. The powerful ...
