Single Molecule Force Spectroscopy Studies JPK Instruments is happy to announce the latest member of their nanotechnology characterisation systems family: the ForceRobot®
new standard in single molecule force spectroscopy.
The key to obtaining meaningful results from single molecule techniques such as force spectroscopy is the statistical management of the results. This is where the new ForceRobot®
300 technology delivers the solution. The automated setup and continuous adjustments provide improvements
in the efficiency of data collection while the integration of optical techniques allows targeted measurements where the molecules of interest are located. These factors, combined with the highest data quality and stability, open the field of single molecule force spectroscopy to a new level of results.
The key to the system is the incorporation of intelligent software for experimental design, data acquisition and evaluation. Tens of thousands of force curves may be generated and evaluated in a matter of hours. To produce high quality curves requires an exceptional instrument with the lowest noise floor and the most rigid mechanical design. The highest accuracy and stability of the instrument is ensured by integrated capacitive position sensors with drift being minimised thorough utilising a symmetrical system design.
The system may be operated in a stand-alone mode to give maximum access and flexibility to the sample. Alternatively, it may be mounted on top of an inverted optical microscope to enable simultaneous force spectroscopy and fluorescence microscopy. Both versions are available with a choice of positioning stage. While the basic motorised stage will provide positioning to better than one micron, the Precision Mapping Stage uses closed-loop control with noise levels to better than 0.3nm with positioning to about 1nm.
Like all JPK’s advanced instruments, the ForceRobot® 300 has many further options for fluidics and temperature control to enable the most reproducible results. New Capillary Gas Chromatograph Drives High-speed Trace Level Analysis
With Advanced Flow Technology, a redesigned suite of detectors featuring market-leading sensitivity, and fast heating and cooling, the new GC-2010 Plus from Shimadzu Scientific Instruments improves separation performance, reduces analysis time, redefines sensitivity limits for trace analysis and ensures data quality for a wide range of applications.
The GC-2010 Plus features Shimadzu’s Advanced Flow Technology (AFT). AFT consists of digital pressure controllers, additional hardware and new intuitive software, all of which provide solutions for improving productivity and enhancing performance. The two new AFT packages are the backflush kit and detector splitting system.
The backflush system discharges high-boiling point components efficiently through the injection port split vent to reduce analysis time, and prevent column deterioration and detector contamination. The detector splitting system splits compounds eluting from an analytical column to multiple detectors to obtain multiple chromatograms. This saves laboratories time and money by providing additional information in a single analysis.
The GC-2010 Plus utilises a family of new, best-in-class detectors. Each detector (FID, FPD, ECD, FTD and TCD) has been engineered using the latest technology, from upgraded cell insulation to an improved collector design, to address increasing sensitivity demands for trace-level analysis.
The compact FPD (flame photometric detector) features improved flame stability and double focusing optics to achieve the world’s highest sensitivity for analysis of phosphorus and sulfur compounds. Utilising clean detector gas flows and the latest noise reduction technology, the FID ensures world-class sensitivity with a minimum detected quantity of 1.5 pgC/s.
The GC-2010 Plus incorporates a redesigned oven enabling rapid heating and cooling. A double-jet cooling system touts optimised air flow channels that enable a rapid cooling time from 450°C to 50°C in 3.4 minutes. Long-term stability of peak retention times is realised by the new room temperature compensation technology built into each Advanced Flow Controller.

Tintometer Launch New Automatic Spectrophotometric Colorimeter for Liquids
The Achema 2009 exhibition saw the launch of a new technological breakthrough from Tintometer. The all new PFXi series of instruments include RCMSi technology (Remote Calibration & Maintenance Service via internet). This unique feature allows a calibrated measurement to be taken using an ISO 17025 certified liquid standard. The spectral response is transmitted to The Tintometer Ltd’s secure calibration server in Amesbury UK. On completion of this procedure a traceable calibration certificate is e-mailed to the user. The RCMSi system not only gives the user added confidence that the instrument is working within tight ISO standards but also reduces the need for expensive on-site servicing and preventative maintenance of the unit.
The large, clear LCD screen allows the display of graphs and data in a wide variety of languages and the easy to use menu system guides operators through the selection of operating parameters. Measurements are initiated by just a single key press.
The accuracy, repeatability and reproducibility of data provided by the instruments allow for tighter colour specifications and greater colour consistency, giving companies the confidence needed to make important decisions regarding high value consignments and refining operations. When measuring Saybolt or Pt-Co Colour of clear, water-white products, the unique long sample path length ensures precise colour measurements, without multiplying errors.
Lovibond® instruments are widely used in industry to
ensure that these colour changes can be monitored reliably and easily, and that industry can ensure their products meet international specifications.
