Chirascan sets new standards for steady-state circular dichroism spectroscopy.  It incorporates innovative optical design features to maximise light throughput, particularly in the far-UV wavelength region, and a sophisticated digital data acquisition system that facilitates the rapid collection of more accurate and precise CD spectra.  Chirascan’s digital CD spectra acquisition approach ensures that unmodified CD spectra are collected and any post-acquisition smoothing of the CD spectra will be non-distorting and completely reversible. This approach also simplifies the operation – Chirascan is as straightforward to use as a single-beam spectrophotometer.

Other key features include:

• Able to collect thermal denaturation CD spectra in a single experiment; enabling identification of the secondary structural changes associated with each phase transition
• 5 detection channels: CD, Absorbance/Transmission, HT, Temperature and Voltage. Simultaneous multi-channel data acquisition ensures that all key information is recorded with every measurement you make
•  Very low nitrogen usage. Rapid and efficient nitrogen purging combined with a sealed monochromator housing ensures that just 5 l/min is required for far-UV work
• Moveable detector. The detector position is easily adjustable and can be set close to the cell to optimised performance with highly scattering samples e.g. membrane proteins

A large range of accessories are available, ensuring the researcher can be confident of a highly effective and future-proof spectrometer that can be adapted as research interests evolve.  These are best explored with the comprehensive brochure available on request.

Chirascan™-plus ACD is the world’s first and only truly automated CD spectrometer. Unattended operation increases the productivity of CD measurements markedly, with up to 200 samples per day now routinely achievable.  The improved productivity transforms the number and type of experiment that can be undertaken and addresses key needs in formulation and bio-comparability applications.

‘qCD’ (quantitative CD) reflects a number novel capabilities that improve performance and enable absolute CD measurements (a first in CD spectrometry).

High Pressure STA and MSB

The ability to measure Heat Flow and Mass loss/gain at high temperatures and pressure is a specialist technique which is gaining interest to have samples tested to have dual sets of data at exactly the same conditions.  Linseis offer the High Pressure STA to meet the needs of research in conditions outside of ambient pressure.  There various configurations possible to cover temperatures from ambient to 1000oC, -170 to 1800oC.  Naturally the selection shall require some discussion and our specialist knowledge built up over years shall be important in our guiding your research interests.  Scientex and Linseis shall be pleased to discuss any project which would benefit from STA where pressure is a key factor in analysis.

Sorption studies at high pressures and elevated temperatures are often associated with corrosive atmospheres.  The principle of the Magnetic Suspension Balance (MSB) has come out of Patent and Linseis has been very active in this technology sector for a number of years.  Linseis offers a great alternative to its competitor.

With the MSB, gravimetric measurements in a wide temperature and pressure range and under aggressive media can be done. An MSB consists of a micro balance for recording the measurement values, a suspension coupling which carries the weight of the sample, a sensor for the position measurement of the levitation part and a control unit to control the suspension coupling.

The contact-less transmission of the sample weight is realized with a levitation magnet and a holding magnet. The levitation magnet consists of a permanent magnet and the holding magnet consists of an electromagnet hanging on the balance. The position sensor delivers the actual position of the levitation magnet and the PID controller makes a stable levitation position with the electromagnetic force as the actuating variable. Through the magnetic coupling a micro balance can be set up at environmental condition. Therefore the balance is protected from high temperatures, pressure and aggressive media.

qCD  (quantitative Circular Dichroism) reflects a number of novel capabilities that improve performance and enable absolute CD measurements (for the first time in CD spectrometry).

• Absolute CD calibration using a multipoint optical standard (absolute CD accuracy to within 1%).
• Precision error bars with each CD measurement
• Significantly higher sensitivity than ALL other CD spectrometers; equivalent to a synchrotron-CD in the 170 – 260nm region.
• Advanced thermal ramping modes mean that structural, stability and aggregation information can be obtained in one 75 minute experiment.
• Low nitrogen purge requirement – just 5 litres/min at 170nm (this compares with around 20 litres/min on other CD instruments).
• pre-set /auto start-up and switch-off of N2 purge and lamp ignition – so the instrument can be ready for use when you reach the lab, and can be left on to complete an experiment when you leave the lab.
