Simple Screening Analysis of Detergent Using a Single Quadrupole Mass Spectrometer

User Benefits

- Simple screening analysis of the components included in detergents such as surfactants can be performed with a single quadrupole LC-MS. - Because of the direct injection by flow injection, high throughput analysis (1 min/1 sample) can be achieved. - By performing multivariate analysis of the mass spectra obtained using eMSTAT Solution™, the characteristic components can be easily found.

Introduction

Detergents like dishwashing detergents contain various components such as surfactants. In order to develop detergents that have greater detergency and are skin-friendly, it is necessary to select the appropriate type and quantity of surfactants. Therefore, for the development and manufacture of detergents, it is extremely important to understand the information on the components included in the detergents. Also, dishwashing detergents are often mixed into beverages and foods. So detailed analysis and rapid screening of dishwashing detergents are important for foreign matter inspection. This Application News describes a method using flow injection and a single quadrupole LC-MS for simple screening of the components in dishwashing detergents. Because samples are injected by flow injection, high throughput analysis is possible and useful for multi-sample analysis. When the sample volume is small, a probe electrospray ionization mass spectrometer, as introduced in Application News No. B118, is useful. Even several µL of a sample can be analyzed.
