High Sensitivity ICP® Accelerometers
-
High sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors. These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor. All units are hermetically sealed in a titanium or stainless steel housing. Models that include a 2-pin, military style connector provide the added benefit of being electrically case isolated for superior RF and EMI protection.

Structural Test ICP® Accelerometers
-
Conventional structural test data systems use few to several hundred sensors. Cables bundles can be complex and confusing resulting in setup errors. Sensors with TEDS (Transducer Electronic Data Sheet) allow for an internal sensor digital chip to store sensor information. This information contains descriptive identifiers that when connected to a TEDS compatible signal conditioner or data system, reads the descriptive information and automatically aligns the data system. Human error is minimized, reducing time consuming data verification or re-test. The Series 333 ICP® accelerometers, and their accessories, are designed to address the needs of multi-point modal and structural test measurement applications. This equipment was developed in conjunction with the world renowned University of Cincinnati Structural Dynamics Research Laboratory and proven in real-world testing situations. The PCB 333 Series accelerometers delivers rapid system setup, reduces human documentation errors, maintains calibration data of each sensor, allows for “Plug-and-Play” installation, reduces overall test time lowering project test costs.

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.
