Single particle optical sizing (SPOS) is a particle size and count technique that provides results at high accuracy and resolution. Particles in liquid suspensions flow through a sensing zone illuminated by a laser beam. Each particle obscures and scatters the incident light source. With the AccuSizer LE-400 sensor, both the light obscuration and scattering are used to relate particle/ light interactions with particle size. Each particle is sized and counted one at a time, providing the concentration in particles/mL. The sample volume must also be accurate in order to generate accurate concentration data. This technical note presents data generated at customer request to prove the size, count, and volume accuracy of the AccuSizer SIS/Syringe Injection Sampler system.
The Agilent 1290 Infinity II High Dynamic Range Diode Array Detection (HDR-DAD) Impurity Analyzer Solution combines the signals from two diode array detectors with different path length Max-Light cartridge cells to increase the linear dynamic UV-range. This solution can be used to detect and quantify main and trace compounds in a single run without exceeding the linear UV-range. Using one DAD with a 10-mm flow cell, typically two injections with different injection volumes are needed to determine low-dose, high-dose, and trace compounds. This Application Note demonstrates that one injection is adequate to reliably quantify low-dose, high-dose, and trace compounds of a fixed-dose combination drug using the Agilent 1290 Infinity II HDR-DAD Impurity Analyzer Solution.
