OmniSIA (FIAlab-3500)

As the name implies, the OmniSIA is built for versatility. By combining elements of flow injection and sequential injection, we are able to achieve unique combinations of high throughput and low reagent consumption.

The OmniSIA can be configured to measure both a sensor’s “impulse response” and “step response”, so the sensor’s performance can be fully characterized in an automated manner. For micro-sized sensors or ultra-sensitive applications where pulseless flow is critical, we will outfit the OmniSIA with a high-precision syringe pump.

This instrument has been used for the following applications: gas diffusion, dialysis, low pressure column separations, the exploration of chemical reactions, and more. As mentioned, the versatility of this instrument makes it a unique answer to many analytical questions. Tell us about your application, and we’ll gladly recommend you the most suitable instrument. We’ll even work with you to build method scripts, protocols, and custom data reports.
