VIP-HESI

The VIP-HESI source generates a higher sensitivity for a broad range of analytes. The vacuum insulated probe (VIP) enhances electrospray ionization efficiency while minimizing thermal degradation of analytes. Matrix is rapidly and efficiently removed from the source via an active exhaust for sustained sensitivity maximizing system robustness with minimal maintenance. The VIP-HESI source also has the capability to switch to APCI mode used for less polar molecules often encountered in environmental, food, and industrial applications.
