The LFSESI is an Add-On Ionizer that turns your MS into a powerful vapor analyzer for health applications
There is growing evidence that physiological processes (either pathogenic or not) have a characteristic vapor fingerprint, which can be assessed either by breath analysis or using culture media. Vapour analysis offers therefore a new universe of possibility for health diagnosis, physiological or pathological studies and pharmacokinetichs.
The new SEADM’s LFSESI (Low Flow Secondary Electrospray Ionizer) allows you to tackle these applications with unprecedented efficiency. Working as a vapor ion source in substitution of the source of your native MS, LFSESI can be seemingly assembled with your current MS (it weighs 5-6 kg depending on MS model) in less than 5 minutes to deliver up to 1000 compounds in real time, with outstanding sub-ppt sensitivities.
Benchmark
Our LFSESI has no rival in the field of vapor analysis. And still at a fraction of the price of a mass spectrometer!
