Harpia-TF -
Light Conversion Ltd.
HARPIA‑TF is a time-resolved fluorescence measurement extension to the HARPIA‑TA mainframe that combines two time-resolved fluorescence techniques. For the highest time resolution, fluorescence is measured using the time-resolved fluorescence upconversion technique, where the fluorescence light emitted from the sample is sum-frequency mixed in a nonlinear crystal with a femtosecond gating pulse from the laser. The time resolution is then limited by the duration of the gate pulse and is in the range of 250 fs. For fluorescence decay times exceeding 150 ps, the instrument can be used in time-correlated single-photon counting (TCSPC) mode that allows for measuring high‑accuracy kinetic traces in the 200 ps – 2 μs temporal domain. HARPIA‑TF extension is designed around the industry leading Becker&Hickl® time-correlated single-photon counting system, with different detector options available.

Dantec Dynamics A/S
Planar laser-induced fluorescence (PLIF) is an optical diagnostic technique widely used in fluid and gas applications. PLIF has proven to be a valuable tool for flow visualization as well as for quantitative whole-field measurements of scalars such as concentration and temperature in liquid and concentration in gaseous flows. Applications can be found in process engineering, biomedical engineering, and fluid dynamics research.

Pharmaceutical Elemental Impurities Analysis System -
Shimadzu Corp.
Control of Elemental Impurities in Pharmaceuticals In the pharmaceutical industry, the analysis of elemental impurities is necessary to ensure the safety of pharmaceuticals. In December 2014, the "Guideline for Elemental Impurities" (Q3D) was issued by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), consisting of representatives from Europe, the U.S. and Japan. In Japan, the "Guideline for Elemental Impurities in Drug Products" (PFSB/ELD Notification 0930 #4 from the Ministry of Health, Labour and Welfare) was issued, and will be applied to new drug products submitted for approval after April 1 2017. For 24 elements categorized in Class 1 to Class 3, residual quantities in pharmaceutical drug products must be controlled within permissible limits. Although ICP-AES and ICP-MS are used for precise analysis of elemental impurities, X-ray fluorescence spectrometers can be used as an alternative analysis method. This is because they can quantitatively and qualitatively analyze a variety of elements nondestructively, and without chemical pretreatment, unlike ICP-AES and ICP-MS systems. The X-ray fluorescence spectrometry has been adopted as a general method of analysis in the U.S Pharmacopeia and the European Pharmacopoeia. (USP<735>, Ph.Eur.2.2.37)

EDX-LE -
Shimadzu Corp.
EDX-LE is an X-ray fluorescence spectrometer designed specifically for screening elements regulated by RoHS/ELV directives. The model uses a detector (Si-PIN semiconductor detector) that does not require liquid nitrogen, thereby achieving lower operation cost and easier maintenance. Automated analysis functions improve operability without sacrificing its high level of inspection reliability. The time required from start of measurement to judgment is as short as one minute for some samples, which is very helpful in screening inspections for elements regulated by the RoHS directive.

MESA-7220V2 -
HORIBA, Ltd.
The MESA-7220V2 measures both sulfur and chlorine in petroleum based products using the Monochromatic Energy Dispersive X-ray Fluorescence (EDXRF) method. A monochromatic X-ray source is used in order to obtain an ultra-low noise background which affords the best detection limits for both sulfur and chlorine.The detector window size was increased to collect more fluorescent X-rays and thus achieve lower level ppm values. This provides excellent, repeatable performance at both low and high concentrations of both elements.By adjusting the angle of the graphite crystal, the excitation beam can be measured to excite sulfur in the sample, increasing sensitivity.

Evans Analytical Group®
Two XRF systems are available, a wavelength dispersive system (WDXRF) and an energy dispersive system (EDXRF). The difference is the manner in which the x-rays are detected. WDXRF instruments have very good energy resolution which leads to fewer spectral overlaps and improved background intensities. EDXRF instruments have higher signal throughput which can shorten analysis times. The higher signal throughput also makes EDXRF systems suitable for small spot or mapping analysis.
