ICP® Shock Accelerometers
-
Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage. The addition of internal mechanical isolation minimizes the high frequency stress that would otherwise be encountered by their ceramic sensing elements. This mechanical isolation, coupled with an internal 2-pole electrical filter, built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz. Depending on the specific model, accelerations in excess of 50 kg can be successfully measured. These modern designs, with their internal elastomeric isolation materials are verified through calibration to remain dynamically linear and are enabling piezoelectric accelerometers to operate in increasingly severe acceleration environments.

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.

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.
