Industrial ICP® Strain Sensors
-
For Process Monitoring/Quality Control. The Industrial ICP® Strain Sensors incorporate piezoelectric quartz sensing crystals that respond to a longitudinal change in distance. The resultant strain measurand is an indirect measurement of stress forces acting along the structure to which the sensor is mounted. As such, these devices can provide insight into the behavior of mechanical systems or processes that generate an associated machinery reaction.

Inductively Coupled Plasma Spectroscopy (ICP-OES/MS), ICP Analysis Services
-
ICP-OES measures the light emitted at element-specific characteristic wavelengths from thermally excited analyte ions . This light emitted is separated and measured in a spectrometer, yielding an intensity measurement that can be converted to an elemental concentration by comparison with calibration standards. ICP-MS (ICP-Mass Spec) measures the masses of the element ions generated by the high temperature argon plasma. The ions created in the plasma are separated by their mass to charge ratios, enabling the identifcation and quantitation of unknown materials. ICP-MS offers extremely high sensitivity (i.e. low detection limits) for a wide range of elements

On-line ICP / ICP-MS Sample Preparation System
SDX ʜᴘʟᴅ
-
The SDXHPLD system combines the proven ASX‑560 autosampler with a novel vortex mixing dilution accessory. The system dilutes in the same way you do by hand: volume-to-volume dilution, using a highly accurate syringe pump. But it also goes an additional step to vortex mix the resulting dilution prior to sample introduction to ICP and ICP-MS.The SDX employs vortex mixing to promote homogenization of a sample to ensure accurate and precise analysis following dilution. The variety of sample matrices submitted for trace element analysis necessitates the need for mixing. This long overdue capability improves data quality by fully homogenizing a dilution mixture rather than performing in-line combination.The SDXHPLD is a straight-forward, fully-integrated solution for automated dilution of aqueous and acid base sample prep for ICP or ICP-MS.

Microphone Arrays
-
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.
