Dopants and Specialty Gases are widely used in deposition processes in the semiconductor and solar industries. To save on transport fees, leading fabs in Asia are moving towards blending Germane at their locations, requiring on-site analysis. Our CRDS analyzers, with cost-saving low flow rates and fast speed of response, are ideal for moisture analysis in Arsine (AsH3), Phosphine (PH3), Ammonia (NH3) as pure gases, and mixture gases containing Germane (GeH4) and Phosphine (PH3) with Hydrogen (H2).
Analyser Helps Safeguard NASA's Juno Mission Against Dangerous Contaminants
Along with NASA scientists, Tiger Optics LLC (USA) had reason to cheer when the Juno spacecraft successfully entered Jupiter’s orbit in July, capping its five-year journey from Cape Canaveral. Prior to Juno’s launch on August 5, 2011, a Tiger Optics trace-gas analyser helped NASA keep the scientific payload in prime condition.
As demonstrated in the Juno mission, Tiger Optics’ HALO trace-gas analyser plays a critical role in detecting contaminants that could compromise the performance of scientific instruments in space. Such scientific instruments are designed to operate in the vacuum of space, in the absence of chemicals present in the earth’s atmosphere: water, oxygen, and particulate matter. Prior to launch, the space-bound instruments must be protected from earthly contaminants by storing the payload under a flow of high-purity inert gas. Nitrogen is usually the inert gas chosen for the task. Typically, the moisture level in NASA’s high-purity nitrogen must be kept under 1 ppm. Tiger Optics’ HALO H2O analyser comfortably handled that requirement for the Juno mission, because the device measures moisture in a range from 2 ppb to 20 ppm.
After Juno entered Jupiter’s orbit on July 4, NASA scientists powered up the science instruments aboard the spacecraft for its first close “flyby” of the planet on August 27. On September 2, NASA reported that all eight of Juno’s science instruments were successfully energised and collecting data. Indeed, on the first of 36 scheduled orbital flybys, six megabytes of data were collected during the six-hour transit of the spacecraft from above Jupiter’s north pole to below its south pole. While analysis of the data is ongoing, NASA quickly published the first-ever images of Jupiter’s north pole.
“Tiger Optics is honoured that its technology is trusted to support our nation’s journey into the frontiers of space,” said Lisa Bergson, Tiger Optics’ chief executive. - See more at: here.
TIGER OPTICS OPTIMIZES AMC MONITORING WITH A MOBILE CART
Tiger Optics LLC, responding to the semiconductor industry’s escalating need to continuously monitor airborne molecular contaminants (AMC) in cleanroom environments, said it is introducing a robust but compact mobile cart to accommodate multiple Tiger-i analyzers that excel in speciating trace amounts of the most vexing contaminants.

The new ALOHA+ H2O advances trace moisture detection in ammonia to an unprecedented level of 2 parts per billion (ppb). The ALOHA+ H2O serves specialty gas and High-Brightness LED makers, as well as those developing advanced materials to power the Internet of Things. It offers the exceptional detection limits, accuracy, reliability, speed of response and ease of operation that you have come to expect.
World’s Most Sensitive Detection of Moisture in Ammonia, ALOHA+ H2O
Tiger Optics has advanced the ALOHA+ H2O, the world’s most sensitive detector for moisture (H2O) in ammonia (NH3), which can detect H2O levels in NH3 down to two parts-per-billion (ppb).

Tiger Optics Qualifies Fuel Cell Hydrogen: Testing fuel cell hydrogen is vital. As Toyota and other automakers bring new electric autos to market, Tiger's analyzers provide the sensitivity, selectivity and accuracy needed to measure contaminants that can damage or destroy a vehicle's fuel cell. In fact, Tiger Optics ranks as the top performer in a 2015 report funded by the U.S. Department of Energy Fuel Cell Technologies Office, entitled H2First Hydrogen Contaminant Detector Task. Of the technologies evaluated from ten different analyzer makers, Tiger's Continuous Wave Cavity Ring-Down Spectroscopy (CW-CRDS) provides the fastest response time, with the lowest maintenance. The report concluded that CW-CRDS is one of the two "most complete commercial-off-the-shelf technologies that could be used in a HCD [Hydrogen Contaminant Detector] application."
Tiger Optics wins California order to test hydrogen for FCEVs
Tiger Optics wins California order to test hydrogen for FCEVs, reported by Fuel Cells Bulletin.
With the impending launch of hydrogen fuel cell vehicles, Tiger Optics promotes its testing of the gas
Spearheading the move to carbon-free transportation, the company announces its most recent order from the State of California to qualify the hydrogen (H2) required to operate fuel cell electric vehicles (FCEV).
Tiger’s analysers provide the sensitivity, selectivity and accuracy needed to measure certain contaminants that can damage or destroy a vehicle’s fuel cell. Because such quality control is crucial for FCEVs to achieve mass-market success, the Society of Automotive Engineers (SAE) International has set stringent standards for hydrogen fuel purity.
The issue is timely, as Toyota begins delivering its Mirai fuel cell electric vehicles to eight California dealerships in October this year. To build consumer confidence, the automaker is offering an eight-year, 100,000-mile warranty on the Mirai FCEV, as well as free fuel for three years. At recent count, only nine hydrogen fuel stations in California were open to the public, but more are in the works.
The California Fuel Cell Partnership—a consortium of private and public entities—expects more than 50 stations to be operational in the state by the end of 2016. Indeed, California adopted legislation in 2013 to allocate $20m annually to build at least 100 hydrogen-fueling stations.
Randy Bramston-Cook, Principal at Lotus Consulting, reports, “We have found the Tiger Optics analysers easy to merge into our complete package, and their detection performance is well below target concentrations.”
The Lotus system incorporates Tiger Optics analysers to screen for three of the damaging contaminants: water, ammonia and formaldehyde, with carbon monoxide analysers pending.
“Tiger is proud to help Californians adopt cars that cut Greenhouse Gas emissions by more than 50% compared to our present vehicles,” states Jeremiah Riddle, Tiger Optics’ President.
The Acid Test: CRDS for HCl Continuous Emission Monitoring
The Acid Test: Faced with more stringent regulation of hydrogen chloride and the need for greater process control, coal-fired plants, cement companies and paper mills seek an effective, efficient and affordable analytical solution. This article offers a first-hand look at Tiger's Journey, from the rarified environment of the US National Metrology Institute to the base of an unheated, 100-meter umbilical at a coal-fired plant in Missouri, and beyond. Along the way, Tiger demonstrated that CRDS technology truly helps our nation's smokestack industries meet their commitments for a cleaner, safer environment.
