仪器简介:
这种4元素火焰光度计增加了钙通道,除了可以直接测试This enhanced four-element flame photometer now features the addition
of a calcium channel. In addition to the features available on the
standard dual channel flame photometer, this new unit allows direct
measurement of calcium with potassium, which are two vital elements
for soil analysis after using Mehlich (111) extraction. Unit allows
you to measure calcium in combination with sodium, and also with
lithium without an internal standard.
This flame photometer can be used as a detector in combination with
multi-channel analyzers from Bran & Luebbe, Skalar, and Lachat. The
system includes its own protocols for calibration, and includes a
special mode allowing you to setup the flame photometer within these
protocols. User selectable signal averaging is designed into the
system allowing you to use these protocols along with analog output
units. Features include automatic ignition sequence, lithium
internal standard, monitoring and control software, dual-channel
display, and independent calibration of each channel. An automatic
gas shutoff mechanism activates if the flame is accidentally
extinguished, or if air pressure drops.
