Tiger Optics’ CRDS analyzers aid in international trace moisture comparison
The main mission of the world’s national metrology laboratories is to establish repeatable and comparable measurement standards across the globe. Measuring trace water vapor in gases is of particular interest because many industries, from industrial gas to semiconductor, depend on this critical measurement. In a recently published international comparison between eight leading national laboratories from Europe, Asia and South America, the labs tested their analytical capabilities in measuring ppm-levels of moisture in nitrogen. Different analytical methods were employed, but most labs relied on Tiger’s robust and easy to use Cavity Ring-Down Spectroscopy (CRDS) technology, with the Dutch VSL, the UK’s NPL, Brazil’s INMETRO, the Swiss METAS and China’s NMI all using various generations of Tiger Optics analyzers. This experiment highlights once again the important role that Tiger’s trace moisture analyzers have played for many years in the metrology community and how our instruments help to obtain an exact analysis with ease. As a company dedicated to precision measurement, we are proud to be able to support the world’s leading NMIs in their important mission.

INRiM researchers develop new low-frost-point generator
All of the world’s leading metrology labs provide a primary reference for water vapor to be able to calibrate humidity sensors against a well-defined and stable standard. Most of these primary references are designed for moisture concentrations and pressures that are more typical for the lower atmosphere. The national metrology institute of Italy, INRiM, took a new approach to provide a primary reference for moisture concentrations that are lower than typical, as demonstrated in their recent publication in Measurement Science and Technology*. This new low frost-point generator is intended for the calibration of humidity sensors designed for conditions in the upper atmosphere, and covers the frost point range from -100°C to -20°C.
To evaluate their new standard, INRiM researchers relied on a pair of Tiger Optics CRDS trace moisture analyzers, one HALO RP analyzer for lower H2O concentrations and one Spark analyzer for the higher range. Both analyzers showed excellent agreement. All measurements are also consistent with the expected value within the reported measurement uncertainty, providing researchers an easy and reliable initial evaluation of their new generator.

Meet the Next-Generation Cleanroom Monitors: T-I Max Series
Building on the success of our proven ambient Tiger-i air monitors, we proudly introduce the next-generation T-I Max series. Airborne Molecular Contamination (AMC) directly affects product yields and the performance of semiconductor fabrication tools. T-I Max monitors, designed to detect trace amounts of ammonia (NH3), hydrogen chloride (HCl), and hydrogen fluoride (HF) in cleanrooms, offer significant improvements in detection limits and speed of response.
Our well-regarded Tiger-i platform of instruments take scant minutes to respond to intrusions, yet the T-I Max NH3 delivers even faster measurement performance and detects down to parts-per-trillion (ppt) level of the contaminant.
With T-I Max, Your Selective Catalytic Reduction Can Curb Ammonia Slip
Ammonia, an odor nuisance at a local level, is a critical atmospheric pollutant in its own right and also a major contributor to the formation of airborne particulate matter. The transport of secondary pollution, as well as ammonia itself, has a negative impact on air quality many miles from its source. It can also corrode plant infrastructure and foul equipment downstream, adding to maintenance costs and downtime at power plants, refineries, kilns, and other industrial combustion sources. Since NH3 is often the reducing agent added to exhaust gas to be adsorbed onto a catalyst, it is crucial to measure and adjust the input efficiently.
Tiger Optics’ Cavity Ring-Down Spectroscopy (CRDS) is ideally suited to the requirements of numerous environmental measurement applications, including process control for selective catalytic reduction (SCR) for these reasons:
- Drift-free, with accuracy traceable to the world’s major national reference labs
- Freedom from interference
- No periodic sensor replacement/maintenance
- Speed of response within seconds
- Wide dynamic range
The low maintenance and calibration-free nature of Tiger’s CRDS technology also affords extremely low Cost-of-Ownership and allows users to operate with confidence and ease in the field.

Tiger Optics Unveils Three New Products
The company will display its HALO QRP (quite reduced pressure) moisture analyser, developed for semiconductor manufacturers using low-temperature epitaxy (LT-Epi). With the shift to lower deposition temperatures and pressures, moisture has become the main culprit in oxide defects. The HALO QRP can monitor each process step and report real-time moisture concentration to the tool control system. The device easily operates at 1 Torr or less, in comparison to the company’ HALO RP, which is limited to 50 Torr.
Tiger Optics is equally focussed on its customers’ growing concerns with ambient molecules that lead to contamination of wafers. The company has therefore developed the new T-I Max platform for continuous AMC monitoring, designed to rapidly measure a specific analyte, with no cross-contamination or interference from other chemicals in the air.
The final product to be unveiled will be the new state-of-the-art AMC mobile cart to package its analysers for cleanroom environments. The cart can accommodate up to four T-I Max analysers and is also fitted with a top-mounted central control touchscreen.
Tiger Optics CEO Lisa Bergson, said, “Building on our decades of work with bulk and speciality gas in the sub-fab, we are also in the cleanroom, serving the industry’s tools and their micro-environments

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’ analyser plays critical role in NASA’s successful Juno mission
The company’s HALO trace-gas analyser played a crucial role in detecting contaminants that could have compromised the performance of scientific instruments in space.
The space-bound sensing instruments were designed to operate in the vacuum of space without oxygen (O2), water or particulate matter and as such needed to be protected under a flow of high-purity inert gas.
Tiger Optics’ HALO H2O analyser was chosen to measure the quality of nitrogen (N2) flow as it can measure any moisture in a range from two parts per billion (ppb) to 20 parts per million (ppm).
Tiger Optics Chief Executive Lisa Bergson was thrilled with the company’s role in the project and stated, “Tiger Optics is honoured that its technology is trusted to support our nation’s journey into the frontiers of space.”
The Juno spacecraft successfully entered Jupiter’s orbit on 4th July, capping its five-year journey from Cape Canaveral and by 2nd September, all eight instruments were successfully energised and began collecting data. Within days, NASA was able to publish the first-ever images of Jupiter’s north pole.
Tiger Optics will be discussing its latest progressions in the Internet of Things (IoT) in the upcoming edition of Specialty Gas Report.
