ECOLOGY:Incorporates a Xenon flash lamp, which is an environmentally friendly, low-power consumption, long-life light source.
Adoption of a Xenon flash lamp
By adopting a long-lasting Xenon flash lamp, the product delivers a long life for its lamp, eliminating the need for periodic lamp replacement that was necessary in previous model*1.
Energy saving design
Through control of the Xenon flash lamp that emits pulses only during measurement, power consumption is reduced by 70% compared with previous model.
Reduced measurement time
The automatic switching of 6 cells by using an automatic 6-cell turret and a high-speed scanning (12,000 nm/min) deliver a substantial reduction in measurement time (approximately 60% reduction). The examples shown in the figure compare*2 the amount of time required to measure 100 samples (5 wavelengths × 20 samples) with a previous model*1, based on biological analyses and quality control on food products.
DESIGN:User-friendly, compact, lightweight design
Compact, lightweight design
The U-5100 features a 38% smaller footprint, and a 52% reduction in weight compared with a previous model*1, which makes it easier to secure an adequate installation space.
EASY OPERATION: Performing at a Higher Level! The operation of the U-5100 is very easy minimizing the operator training time
The standard configuration of an automatic 6-cell turret makes performing measurements a breeze. As part of its standard configuration, the system is equipped with a 6-cell turret which accommodates up to six 10-mm rectangular cells.
The system can measure a maximum of six calibration solutions and sample solutions*3, which reduces measurement time.

*2Measuerment time does not include the amount of time required by an operator to load a cell on a holder or a turret.
*3Including samples for setting an auto zero (the operation of adjusting the absorbance to zero).

Example of application
Quantitation of hexavalent chromium
An example of quantitative analysis of hexavalent chromium by diphenylcarbazide absorptiometry is introduced here. As a result of creating a working curve within 0 to 0.8 µg/mL, a correlation coefficient of 0.9999 was obtained, proving an excellent calibration relationship.
Measuring wavelength: 540 nm
Concentration of standard solution: 0, 0.04, 0.1, 0.2, 0.5, 0.8 µg/mL
|The system withdraws a sample from a test tube and can automatically measure it.|
|Single cell holder
|The system can measure square cells with a 10-mm optical path on a single-cell basis.|
|Rectangular long path cell holder
|The system can measure square cells with 10, 20, 30, 40, 50, and 100-mm optical paths on a single-cell basis. The use of cells with long optical paths allows the system to measure low-concentration samples at a high degree of sensitivity.|
|Micro quartz cell 10 mm
|The system is well-suited for the measurement of micro-volume samples.|
|Black quartz micro cell 10 mm
|Mask for micro cell
|This system is used with non-black-walled micro cells in the sample and reference position and to attenuate the reference beam when using self-masking micro cells in the sample position.|
