NH4+ Ionization for Explosives and CWA Detection

Crucial application benefits from fast switching NH4+ ionization

The proprietary and IONICON exclusive method of producing NH4+ solely from H2O vapor and N2 in the established hollow cathode ion source, without the need of any ammonia (PCT application submitted) has many advantages.

Today we would like to introduce a promising application field where NH4+ is the ideal reagent ion. The unambiguous and highly sensitive detection of explosives as well as chemical warfare agents.

TATP real-time detection

Analyzing the headspace of some µg of the infamous explosive TATP with NH4+ reagent ions boosts the TATP.H+ signal by a factor of 20 compared to the H3O+ mode, because of suppressed fragmentation. Additionally the cluster TATP.NH4+ is formed at an even higher abundance. Thus, by using TATP.NH4+ as an additional detection marker, also the selectivity is considerably improved in “NH4+ mode”.

Live tests and real-time detection of CWAs

The nine most important CWAs (including Sarin, Tabun, Soman, VX, Lewisite, Cyclosarin, Nitrogen mustard and Sulfur mustard) have been investigated at a facility specialized and licensed for CWA handling.  (more…)

The New Exclusive SRI-MS Reagent Ion: NH4+ and Its Benefits

A novel proprietary method of NH4+ production for IONICON customers

In PTR-TOF-MS traditionally H3O+ reagent ions produced from H2O vapor are used. NH4+ reagent ions have been mentioned in literature as being particularly beneficial because of higher sensitivity (less fragmentation) and higher selectivity (higher proton affinity). However, so far toxic and corrosive ammonia was needed for NH4+ production.

We developed a novel method of producing NH4+ solely from H2O vapor and N2 (gas cylinder or filtered air) in the established hollow cathode ion source, without the need of any ammonia, by adjusting the pressure and electric fields in the source (PCT application submitted). That is, the reagent ions can be rapidly switched. (more…)

Free download of Contributions to the 8th PTR-MS Conference 2019

All abstracts from the 8th International PTR-MS Conference are now online

In February 2019, the must-attend event for all PTR-MS users took place, attracting more than 100 participants from 18 nations. There’s a short review if you would like to know more.

Have you ever wondered what this huge number of IONICON instrument users achieves with their instrument, what they investigate, which complex processes they capture or industrial VOC monitoring challenge their solve with our instruments?

New IONICON Extended Volatility Range (EVR) PTR-MS

Ultra-Fast Time Response Even for IVOCs & SVOCs

Real-Time Ultra-Sensitive trace VOC analyzers from IONICON are known for their response times in fractions of a second and hence are often used to follow rapidly changing processes and VOC signals. However, some substances are known to show a slower instrumental response because of unwanted surface interactions. These substances are either highly polar or have a reduced volatility and are typically classified as „sticky“ compounds.

IONICON’s new EVR PTR-MS: ultra-fast response times for IVOCs & SVOCs

With IONICON’s new Extended Volatility Range (EVR) setup we minimize unwanted surface interactions and still preserve all the advantages of our fully pressure controlled inlet system. This extends our sub-second response from VOCs to a wide range of compounds in the intermediate-volatility range (IVOCs, e.g. 2-tridecanone and vanillin) and even reduces the response of semi-volatile species (SVOC) like cis-pinonic acid to single-digit seconds.

The 8th International PTR-MS Conference, Innsbruck, Austria – a review

Must-attend science forum attracted over 100 conferees from 18 nations

At the beginning of February 2019, the International PTR-MS Conference was held for the 8th time. Ever since the first International PTR-MS Conference in 2003, organized by the Institute of Ion Physics of the University of Innsbruck and sponsored by IONICON, the event became a fixed point in the scientific agenda of many of our international peers.

Talks at the 8th International PTR-MS Conference took place in a historic venue of the University of Innsbruck

Since then the conference evolved, attracting more and more participants filling larger venues. If at the very beginning technology enthusiasts and early-adopters were gathering to exchange and network on their experiences with the first IONICON Quadrupole-PTR-MS instruments, the meeting soon became the PTR-MS event for all IONICON instrument users. The program comprised a selection of parallel sessions covering the very broad field of applications that modern PTR-TOF instruments are successfully used in. (more…)

Taking CHARON PTR-TOF to the Sky

At the Frontier of Airborne Research aboard NASA’s Flying Laboratory

Using the opportunity provided by NASA’s Student Airborne Research Program (SARP) we gave wings to our newly developed CHARON aerosol inlet. In cooperation with the University of Oslo our team combined CHARON and a custom built PTR-TOF 4000 instrument.

“Business Class” for our airworthy CHARON PTR-TOF 4000, monitoring VOCs & aerosol in real-time.

Airworthiness requires withstanding of heavy G-forces, coping with pressure changes and most importantly being fail safe. Therefore unique modifications to CHARON have been made and thoroughly tested before getting airborne. (more…)
