Shimadzu Launches Compact UV-VIS Spectrophotometer to Increase World Market Share: Powerful Basic Performance and USB Memory Enhance Ease of Operation

Shimadzu Launches Compact UV-VIS Spectrophotometer

Shimadzu launched the UV-1800 compact UV-VIS spectrophotometer for sale in Japan on 22 August. Its compact design occupies a 15% smaller footprint than the model it replaces, the UV-1700. This standalone instrument can conduct measurements independently, and the UVProbe software supplied as standard uses USB memory to make it easy to conduct data analysis and printing at any PC. The simplified operating procedure allows the user to start measurements just 30 minutes after installing the instrument. The UV-1800 was exhibited at the JAIMA SHOW 2007 held at Makuhari Messe in Chiba from 29 to 31 August.

* UV-VIS spectrophotometers shine visible or UV light onto a chemical, metal, or non-metal sample (usually a solution) and measure the amount of each component from the degree of absorption of the light. They are used for R&D and quality control applications in the pharmaceutical, food, chemical, environmental, and life science fields.

Background to the Development of the UV-1800

The scale of the market for wavelength-scanning UV-VIS spectrophotometers around the world is estimated to be about 25,000 instruments per annum. In Japan, the US, and Europe, the market is primarily a replacement one as users upgrade existing instruments, whereas growth is expected to be approximately 7% per annum in China, India, and S.E. Asian regions that are experiencing rapid industrialization, especially in the pharmaceutical industry. UV-VIS spectrophotometers in the class of the new UV-1800 form the core of this expanding market and are expected to maintain a 35% share of the market.
Shimadzu’s first step to increasing its share of this world UV-VIS spectrophotometer market is the introduction of the compact, standalone UV-1800. There is a strong demand for this type of spectrophotometer in universities and other educational establishments and for research and quality control applications in the pharmaceutical and chemical industries. Shimadzu aims to capture at least 25% of the world market share for instruments in this class in 2008.

The features of the new UV-1800 are outlined below.

More Compact: Unit Reduced in Width by 20%

To meet the demands of many customers, Shimadzu reduced the instrument footprint. Compared to the UV-1700, the width has been reduced by 20% to 45 cm, decreasing the installed footprint by 15% (450 mm W x 490 mm D). The unit can be installed close to other instruments.

USB Memory Sticks Allow Data Analysis and Printing by a PC

The UVProbe data processing software that was previously sold separately is now installed as standard. Just drag and drop the data saved in a USB memory stick onto the UVProbe icon in the PC to display the spectral lines for immediate analysis or printing. This is the first time that a standalone instrument in this class has offered such a function. Using the macros and graph functions offered by commercial spreadsheet software can reduce effort and significantly enhance work efficiency.
Moreover, connecting the instrument to a PC using the optional USB interface allows PC control of the UV-1800. While this is a standalone instrument, diverse data processing can be handled by a PC.

Improved Ease of Manipulating Measured Data

The USB memory can save spectral data, quantitation values, and measurement parameters. When measuring multiple spectra, the spectral data can be automatically saved to USB memory, which avoids the task of resaving the files. In addition, the USB memory can also save the parameter settings, which is very useful when multiple users share a single instrument.
Measured data can be printed on an ESC/P printer*1 or a PCL printer*2 with a USB interface, which greatly expands the range of printers that can be used.
*1 ESC/P printer: Printer manufactured by EPSON
*2 PCL printer: Printer compatible with the Printer Control Language developed by Hewlett Packard

Simple Design and Even Easier to Use

The number of operation keys has been minimized and the spacing between them has been increased to allow trouble-free instrument operation. The USB memory stick is fully enclosed within the unit when inserted. The display screens are simple and retain the ease-of-use of previous models. There are only three screens: parameter settings, progress status, and results display. Anyone replacing an instrument with this one will be able to use it immediately.

Enhanced Basic Performance, Including Reduced Stray Light* and Noise Level

Shimadzu’s unique technologies enhance the basic performance of the instrument. The optical mechanism from a high-end instrument is used in the monochromator that turns the light from the light source into monochromatic light. The brighter optical system reduces the noise level (at 700 nm) to 1/4 that of the UV-1700 instrument. The Shimadzu LO-RAY-LIGH low stray light diffraction grating was used to successfully restrict the stray light* to half that in the UV-1700 (at NaI 220 nm/NaNO2 340 nm). Baseline fluctuation is also reduced to below 1/3 (at 700 nm).
* The amount of non-target light (wavelengths) in the optical system.

1 nm Wavelength Resolution is the Highest in this Class

The 1 nm wavelength resolution inherited from the UV-1700 is the highest level in this class, including at the conditions demanded in the European Pharmacopoeia* (the ratio of the peak maximum at 269 nm to the minimum at 266 nm in a 0.02% v/v solution of toluene in hexane).
The validation function installed as standard to validate the hardware uses a wavelength-correction optical filter corrected at 1 nm to permit hardware validation according to the Japanese Pharmacopoeia*.
* A Pharmacopoeia is an official standard that prescribes the quality of pharmaceuticals and the quality test methods. Pharmacopoeias are established in several dozen countries around the world.
