Using
a reconfigured grating monochromator from the successful M105 and
M106 models, the M107 offers more performance and versatility with
only a modest price difference. The large sample compartment allows
the use of a wide range of accessories, including a 4-position cell
changer with holder for cell pathlengths up to 50mm. A membrane keyboard
positioned next to the large, clear LCD display allows the operator
to rapidly switch between %T, Abs and Concentration modes, and to
set Zero Abs.
Signal
processing and results display are microprocessor controlled and
the narrow 5nm bandpass gives improved analytical sensitivity. The
outstanding optical performance is also indicated by the low zero
drift (<0.001A/hr) and the low stray light (0.1%T @ 340nm). The
fundamental reliability of the instrument is assured by the absence
of motor drives - wavelength selection is by rotary control. This
simple mechanism automatically selects the order sorting filters,
offers permanent wavelength calibration and eliminates wavelength
initialisation routines at switch-on.
The
RS232 output provides a convenient link to a PC or a digital printer
for hardcopy. A low-cost application program which runs under Windows®,
includes the facility to create calibration curves. The reaction
kinetics program, when used with the thermostatted cell holder accessory,
provides an excellent low-cost enzyme analysis system.
