Research Grade Light Scattering Instrument for Teaching Labs
Testa Analytical Solutions eK reports how the internationally respected Department of Chemistry at the University of Helsinki is using its BI-200SM light scattering goniometer for physicochemical characterisation of polymers.
Dr Vladimir Aseyev, a senior lecturer in Polymer Chemistry at the University of Helsinki said: “Based upon practical use of our BI-200SM light scattering goniometer we organise a course of lectures on light scattering for students as well as a laboratory practicum. These activities attract students and researchers from other departments such as physics, biology, pharmacy, food science and medicine.”
Dr Aseyev added: “Simple design and easy alignment are the main features that differentiate the BI-200SM from other commercial light scattering instruments. In a combination with the user-friendly software, it is very easy instrument to demonstrate to students how the method and data analysis work as well as what are the limitations of other commercial instruments. The latter is especially important for the students, who continue their career in industry, where single angle light scattering detectors are more common. Recently, with the help of Testa Analytical we upgraded the computer, software and the motor for our BI-200SM. We received very professional advice as well as fast and clear technical support from Testa, who clearly understand the needs of universities and have always been most helpful.”
The Bl-200SM light scattering goniometer is a precision research grade instrument designed for precise and accurate measurements. Based on a special turntable with precision ball bearings and stepping motor, the Bl- 200SM’s modular, automated design and quality construction guarantee precise measurements due to the wobble- free movement of the detector. As you would expect from a research grade system the BI-200SM can measure light scattering over a wide angular range (8° to 155° with 25 mm cells) and offers fi ne adjustment of measurement angles to 0.01° directly using a large, fi ne-control knob or PC-driven Motor control. Fine-screw vertical adjustment makes centre of rotation measurement easier when aligning cells. Precise repeatable data is ensured by automated heating and cooling of the sample cell using and standard external recirculating system. Field proven in hundreds of labs around the world the BI-200SM light scattering goniometer system is ideal for even the most demanding macromolecular studies and submicron particle sizing applications.

Preparative and Semi-preparative LC Autosampler
Are you looking for a preparative or semi-preparative LC autosampler for your sample purifi cation? Maybe during your preliminary product search you have just found very expensive solutions or shoddy devices.
HTA are pleased to show you the perfect instrument for your sampling needs: the HT1500L.
The HT1500L is a LC autosampler, compatible with any HPLC systems, that lab technicians describe as ‘reliable, easy to use and high-performance’.
Besides standard analytical confi guration, the HT1500L can be confi gured as both a semi-preparative and a preparative autosampler to perform robust, precise and accurate large-volume injections for fractioning and purifi cation of samples.
For preparative applications, the HT1500L can mount loops with volumes up to 30ml.
The full-loop injection technique assures high repeatability of the injection and excellent performance. The sample carousel can hold vials up to 40ml to allow a considerable sample loading and a consequent successful purifi cation.
In addition, the large solvent capacity and the infi nite waste makes the HT1500L suitable for semi-prep and preparative HPLC and allows needle and whole fl ow path cleaning before processing the next sample to minimise carryover.
New Reference Standards Target Mycotoxins in Cannabis
Mycotoxins are toxic secondary metabolite compounds produced by mould or fungi. Due to the toxicity of certain mycotoxins that can be found on cannabis plants, there is a growing need to detect their presence in both raw plant materials and fi nished cannabis products.
Restek now offers two new mycotoxin certifi ed reference materials (CRMs): Ochratoxin A and Afl atoxins (B1, B2, G1, G2).
These new reference standards enable labs to expand their cannabis analyses with a Restek solution when coupled with the its high- throughput Raptor ARC-18 LC column.
