Our team aims to develop convenient and reliable solutions
based on state of the art technology and the world
leading scientific expertise. We address the emerging
challenges of globalizing world and accelerating
communication by increasing transparency of the flow
of things and people.
MTTD-ONE is a concept designed for transportation and
logistics security with the special focus on automated
luggage and parcel screening for explosives detection.
This solution is applicable in transport nodes, logistic
hubs and critical infrastructure.
Our first prototype has been tried in a pilot test
at the Helsinki-Vantaa airport's baggage handling area.
The test has been successfully concluded in summer 2016.
Extreme sensitivity combined
with high selectivity and speed
Using proprietary technology we have achieved superior
sensitivity in detecting explosives and hazardous
chemicals. Record breaking 1 part per quadrillion *)
detection threshold achieved for RDX **) and PETN
***), the two explosives most commonly used in acts
of aviation terrorism.
The current MTTD-ONE device is capable of ultrahigh
sensitivity detection of the following explosives
and related species
Currently we are optimizing the system for detection of
Nerve Agents And
* 1 part per quadrillion = 1 molecule of target substance in million billion ( 1015 ) molecules of air. Diameter of a hair corresponds to 1 part per quadrillion of distance between Earth and Sun.
** RDX in acts of terrorism: 1993: Bombay bombings – 1999: Russian apartment bombings – 1999/2000: Ahmed Ressam, the al-Qaeda Millennium Bomber Los Angeles International Airport bomb plot – 2004: Russian aircraft bombings – 2005: assassination of Lebanese prime minister Rafiq Hariri – 2006: Mumbai train bombings – 2008: Jaipur bombings - 2010: Moscow Metro bombings. RDX is also used as detonating compound in C4-plastic explosive.
*** PETN in acts of terrorism: 1983: the "Maison de France" house in Berlin. – 2001 "Shoe Bomber’s" attempt to bomb the American Airlines Flight. – 2009: attempt to murder the Saudi Arabian Deputy Minister – 2009: attempt to bomb the Northwest Airlines Flight - 2010: cargo plane bomb plot in Dubai on flights bound for the U.S.
Speed & Selectivity
Continuous sampling from existing conveyor systems.
No need to stop the cargo line
Simultaneous detection of all species. Unlike most mass spectrometric methods our mass analyzer detects all substances simultaneously
False positives minimized.
Superior selectivity guarantees that no alarm is set due to harmless compounds
Sampling in less than a second. Screening rate of more than thousand objects per hour
Record speed of response
(< 5 seconds)
100% high volume
Detection with online signal processing and interpretation
How it works MTTD-ONE
and desorption unit
Do you endeavor better public or private safety
and keen to know how
our technology might help?
With an increasing flow of people, luggage and cargo partial sampling at times fails to be sufficient. In terms of transport security and public safety it induces an overwhelming pressure on security systems and passengers. Here at KARSA , our goal is to provide the solution that is capable of 100% high-resolution screening at the same time fast and convenient for security operators and travelers.
DarkNet black markets utilizing conventional carriers to distribute illicit substances and recent grievous events
of China parcel bombings have shown that logistic hubs can be very vulnerable. KARSA is able to provide solutions for screening more than 1000 parcels per hour, delivering high level of security without slowing down the exchange of goods.
Critical infrastructures have always required high level of security in order to restrain incoming and outcoming threats. It is important to conduct screening operations with sufficient accuracy and
in the most convenient way possible not to disrupt the operations of the organization. KARSA provides solutions that are ultrasensitive, autonomous and convenient to use in a wide range of environments.
Who we are
Karsa Ltd is a spin-off company supported by University of Helsinki,
international industry partners
and venture capital.
As part of the university project, group led by Dr. Mikko Sipilä* started working on adaptation of technological know-hows to detect explosives in 2013.
In 2016, we have developed a prototype of one of the most sensitive detectors in the world, versatile in use of application and capable of bringing public safety to the new level. The concept was successfully tested at the international airport and now we concentrate our efforts to make it complete as a company!
