Agilent 500 Ion Trap LC/MS System can quickly switch ion polarity to realize real-time positive and negative ion detection

The Agilent 500 Ion Trap LC/MS has high mass sensitivity and is ideal for trace investigation.

Advantages of reduced noise with the Agilent 500 Ion Trap LC/MS Ion Optics. The API interface and ion coupling optics in the 500 Ion Trap have unique features that reduce the chemical noise from the solvent. The ion guide axis is tilted at an angle so that large solvent clusters and micro droplets pass through the ion guide and do not enter the coupling optics, eliminating large noise spikes in the spectrum. The ion coupling and gating optics further eliminate high energy, multiply charged ion clusters from entering the mass analyzer. The cross section of the coupling optics show ions leaving the API interface capillary and passing through the skimmer cone into the ion guide where collisions with the surrounding gas thermalize their kinetic energies. Ions exiting the ion guide in one section of the vacuum chamber are focused into a second lower pressure region of the vacuum system by the 'ion guide exit' and 'ion guide focus' lens.

This document provides a technical overview of calibrating Agilent PLgel 3 µm 100Å columns using polystyrene standards for GPC analysis. Agilent PLgel 3 µm 100Å columns are designed for the analysis of low molecular weight discrete molecules in organic solvents. The molecular weight information of a sample is calculated by analyzing a series of narrow distribution polymers of known molecular weight and generating a standard calibration curve. This example demonstrates the typical calibration data using polystyrene narrow standards in tetrahydrofuran.
