8 Free Microplate Reader Software Upgrade
Busy laboratory environments require a microplate reader with the flexibility to cover many assay types, and software that delivers fast, reliable analysis. With this in mind, Biochrom are offering a free software upgrade from ADAP 2.0 Basic to ADAP 2.0 Plus with purchases of the EZ Read 400 research reader until 30 September 2011.
The Biochrom EZ Read 400 research reader is a robust and reliable microplate reader with eight pre-installed filters covering the most common laboratory assays. These include: ELISA (405, 450 and 492nm), protein (562, 595 and 650 nm), and cell proliferation (570 and 620nm) assays. The EZ Read 400 connects to any PC via a USB port.
ADAP 2.0, a new software release from Biochrom, offers the user a more intuitive way of interfacing with Biochrom microplate readers, and is compatible with Windows 7 as well as older Microsoft Operating Systems. ADAP 2.0 Basic is supplied as standard and is used to remotely control the reader for basic endpoint, kinetic and multi-wavelength measurements with easy export to MS Excel. ADAP Plus 2.0 allows the user to configure the placement of controls, standards and samples on the plate layout. These can then be used to calculate quality control formulas, cut-off values and standard curves using linear regression, cubic spline, point to point and 4-parameter fit algorithms for immediate results following microplate measurement.

MASS SPECTROMETRY & SPECTROSCOPY
The XRF Solution for Petrochemical Industry
New Measurement System for Quality
Inspection of Solar Simulators Ocean Optics has introduced a new optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The RaySphere allows users to measure absolute irradiance over different spectral ranges from the UV to the NIR (380-1700nm).
The portable RaySphere is especially useful to solar simulator manufacturers and R&D labs as a tool to validate the output of installed solar flash lamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements. For the verification of such solar flashers Ocean Optics developed RaySphere – a system that provides the necessary accuracy and resolution to measure and analyse the performance and stability of the flasher, with advanced, ultra-low jitter triggering electronics for timing the measurement to the flashes. The calibration of the RaySphere has been validated by an accredited certification lab to ensure accurate detection, allowing you to evaluate and qualify the spectral distribution of your solar flashers and simulators according to the IEC60904-9 (2007) norm.
The RaySphere includes two thermo-electrically cooled detectors allowing highly repeatable and accurate spectral analysis of your solar flashers from 380 to 1700nm. A second version contains a single cooled detector for measurement to 1100nm.
Through the whole lifetime of petrochemical products (oil, polymers, chemicals) from the production to disposal, thermal treatment or use as secondary fuel, X-ray fluorescence analysis (XRF) is the most suited analytical method to support all those different applications.
Bruker AXS has developed the specific XRF solution to support all petrochemical applications based on XRF: PETRO- QUANT. It provides quick and easy quantitative elemental analysis for process and quality control laboratories with the world class wavelength dispersive X-ray fluorescence spectrometer S8 TIGER. PETRO-QUANT produces accurate and precise analytical results straight out of the box as the wavelength dispersive X-ray fluorescence spectrometer (WDXRF) is calibrated for a wide range of applications. It frees therefore the operator from time consuming calibration work, saving weeks of commissioning, to ensure the pay back begins from the very beginning.
For general analysis of hydrocarbon matrices, such as fuels and lubricants, the universal PETRO-QUANT calibration is used. It enables standardless analysis for all required elements (more than 30) from Sodium (Na) to Lead (Pb) covering concentrations from trace elements ppm) to major levels (%) (e.g. for S and Cl). For compliance with international norms such as ASTM, DIN, IP or EN ISO, samples must be analysed against norm specific calibrations. PETRO-QUANT even supports these standards with detailed instructions and specific suites of calibration solutions.

The system also includes advanced, high-speed electronics and an intuitive and powerful software interface. Extremely brief measurement times enable the detection of a complete spectrum during a flash or even during a portion of the flash. In addition, the measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub- microsecond response times.

Raman Spectroscopy New Wonder Material
The Nobel Prize in Physics 2010 was awarded to Professors Andrew Geim and Konstantin Novoselov for their isolation and characterisation of the novel advanced material graphene. First report in Science in 2004, graphene consists of a single-atom-thick sheet of carbon atoms arrayed in a honeycomb pattern.
It is the thinnest, yet strongest, material known, being both brittle and ductile simultaneously. Thus, it exhibits excellent transport properties which make it a promising material for future nanoelectronic devices, namely for high-electron- mobility transistors (HEMT).
Due to its scale and optical properties, graphene is hardly visible on most substrates. However, distinguishing the number of graphene layers as well as quantifying the impact of disorder on its properties is critical for the study of graphene-based devices.
Raman micro spectroscopy has proven to be very sensitive for determining both of these properties. Indeed, with its high structural selectivity, combined with both spectral and spatial resolution, this technique can detect edges or defects at the micron scale. The strong Raman efficiency of the graphene enables to cover large surfaces in record time and thus localise mono-, bi- or multi-layers very rapidly. The non-destructive nature of this technique is also a considerable advantage to protect the quality characteristics of this wonder material.
