Environmental Analysis Ocean Optics Spectrometers Head to Mars
Three Ocean Optics (Netherlands) instruments have begun their eight month journey to Mars. Customised HR2000 spectrometers are a part of the ChemCam unit on NASA’s Mars Science Lab rover, Curiosity, launched November 26, 2011 from Cape Canaveral, Florida.
Ocean Optics supplied three modular HR2000 high-resolution miniature fibre optic spectrometers that were configured for analysis of Martian rock and soil composition using Laser Induced Breakdown Spectroscopy (LIBS). A laser mounted to the mast unit of the ChemCam instrument can fire at targets up to nine meters away, generating a series of laser pulses, the light from which is collected for the LIBS analysis.
The modular design of the HR2000, with selectable optical bench options such as detector, grating and entrance aperture (slit), made it an ideal choice for the mission. Each ChemCam spectrometer is configured to detect elemental signatures over a different wavelength of light: 240-336 nm, 380-470 nm, and 470-850 nm. The use of the three spectrometers simplifies the design and creates redundancy, as many elements under study have spectral lines in more than one of the spectral ranges covered by the three units.
Another reason the HR2000 was chosen for this mission was its reliability – a must for remote space operation where maintenance is impossible. Because the spectrometer contains no moving parts to fail, it can withstand the G forces associated with space travel. Additionally, the spectrometers were modified to handle extreme temperature ranges, radiation, shock and vibration.
The Curiosity Rover has been described by NASA as having the most advanced scientific instrumentation ever used to study the surface of Mars. With the analysis enabled by Ocean Optics’ equipment, sample analysis is exponentially faster. On prior missions, the time required to determine composition of a single sample was two to three days; ChemCam’s output is anticipated to be one dozen compositional measurements per day.
This is not the first space voyage for Ocean Optics equipment. In 2009, the company also collaborated on the ALICE spectrometer, which was instrumental in detecting the presence of water ice on the moon. Other NASA researchers have utilized Ocean Optics spectrometers for applications both on Earth and in space.
Reader Reply Card No. New Inlet Dissolved Gas and Vapour Monitor
The Hiden Analytical (UK) HPR-40 Membrane Inlet Mass Spectrometer series now feature an extended range of submersible insertion probes and flow-through semi-permeable membrane interfaces, specifically engineered for measurement of dissolved gases and vapours in aqueous solution in diverse environments and applications.
The systems provide real-time analysis of biological and physical processes within aquatic and marine processes, with interfaces refined for specific applications including bio-fuel development, soil analysis, water quality determination, fermentation culture monitoring and photo-responsive Single membrane flow-through interface processes.
The compact mass spectrometer module is bench-top and cart-mounting compatible, with comprehensive control and data analysis programs for both automated and manual operation. Multiple
sampling lines can be accommodated for automated sequential multi-media sampling, the QIC BioStream variant currently operating with up to 80 sample streams. A custom-design service is available to assist with interface design for specific R&D projects.

New Diaphragm Pump Offers Minimum Format With Maximum Efficiency
The dual model of the SP 100 EC miniature pump fromSchwarzer Precision (Germany) offers pump technology at the highest level
With the world’s smallest diaphragm pump SP 100 EC as dual model 100 EC-DU Schwarzer Precision offers first-class miniature pump technology in its most compact format.
The light-weight of 15 g with a size of only 13 x 22 x 32 mm finds it use especially were condensed design is very important. As all eccentric diaphragm pumps of the SP 100 series the SP 100 EC-DU distinguishes itself through lowest current consumption and is therefore especially suited for portable analysis devices.
Two of the latest technical innovations from Schwarzer Precision make the pump a top product: Maximum flow rates and flow-optimised delivery channels in the pump head are achieved with the TN technology (“No Turbulence Technology”). The active balancing system IBE (Individually Balanced Eccentric) provides extreme quietness of running as it is otherwise found only with much larger pumps.
Utilising the opposing plunger principle the dual pump allows delivery of two different media in parallel. It is equipped with two identical pump heads each of which is operated by the same shaft end of the motor. This means optimal utilisation of the design volume and thus minimum space for dual pump performance.
The modular design of the SP 100 EC pumps permits the exact configuration of the SP 100 EC-DU with a wide variety of diaphragms, valves and motors according to application-specific aspects. Thus it represents an optimal and economic pump solution for all individual customer demands. In its current version with electronically commutating motor it is also the smallest brushless pump worldwide. Its integrated electronics makes separate selection electronics obsolete.
Reader Reply Card No. 104 Submersible Fluorometer Now Available
Turner Designs (USA) is excited to introduce a 6000 meter version of our very popular Cyclops-7 Submersible Fluorometer. The Cyclops-6K is presently available for Chlorophyll, Crude Oil, and CDOM detection with more optical configurations available soon. The reinforced Titanium housing and specialized optical head allow the Cyclops-6K to reach abyssal depths. Offering the same low power requirements, high performance, and long-term stability as the Cyclops-7, the Cyclops-6K is designed with system integration in mind. The Cyclops-6K analog output is easily
integrated into CTDs, ROVs, or AUVs to monitor the deepest parts of the ocean. Similar to the Cyclops-7’s optoelectronics and circuitry, the Cyclops-6K provides an easy-to-use output format over the same connector type.

Horizon Technology (USA) introduces its new SmartPrep Extractor delivering unprecedented versatility for automating tedious manual cartridge-based SPE methods
SmartPrep™ is the first automated, small footprint, SPE extraction system designed specifically for cartridge based sample prep on a wide range of contaminants found in clean aqueous and organic matrices. SmartPrep combines intelligent graphical software, versatile hardware and ease of use to simplify and automate SPE.
Single or multiple module scalability makes automation affordable for bench chemists and method developers as well as high volume commercial sample prep laboratories. Total flexibility means unique SPE methods can be applied to any sample. Eight SmartPrep modules controlled from a single computer process up to (96) samples for excellent walk-away capability and the system is compatible with standard 1, 3 and 6mL cartridges. Many differing sample matrices and volumes ranging from 1.0 mL to 1.0L are easily accommodated.
