The other sprayers in your list are commercial devices which come bundled with their own software as dedicated instruments. In general, all the devices are able to deliver a spray deposition on a surface. These are currently the main difference, but I expect for some vendors to pick up our ideas and implement them in their devices 😉 :
- The iMatrixSpray can autonomously deposit up to 3 different liquids and automatically cleans itself – no interaction required. No other device can do this.
- The iMatrixSpray is completely open for your modifications. All the software is freely available and by using generics electronics there is a large community who is developing software. You want to add a heated surface for drying or a layer thickness monitor? Just do it, it’s open. This is unique.
- The iMatrixSpray comes with a warranty on the parts only (in contrast to the other sprayers). In the unlikely case of a part failing, you don’t have to send back the whole device for repair but you’ll get a replacement part for your own mounting. But with the simple design, there’s no part which could not be replaced by you within 10 minutes. Other manufacturers offer full on-site support.
- The iMatrixSpray was optimized for best sensitivity, reproducibility and homogeneity in MSI. Other sprayers might be better suited for specific applications, e.g. ultimate resolution by semi-dry deposition. But having stated this, we just didn’t test this on our device yet…
