Measuring acid rain residues on leaves and plants
using the Lazar Micro combination pH electrode.
Acid rain due to atmospheric contamination resulting from various
kinds of industrial process plants has become an important area of
environmental study in recent years. An ideal way to study acid rain
residues is to actually measure the pH of individual rain droplets as
they are deposited on various kinds of leaves of plants and trees and
even on individual blades of grass. The problem with this kind of
analysis has been the availability of a small but rugged pH electrode
which can be used in the field with a portable pH meter. The electrode
tip needs to be small enough to measure individual drops of rain.
The Lazar micro combination pH electrode is ideally suited for these
field acid rain measurements. Not only will the probe measure the pH
of one drop of liquid but it is also extremely rugged having a flexible
Teflon stem. It features a solid state pH sensor with a low output
resistance making it very stable in both field and lab situations.
It plugs directly into any laboratory or portable pH meter and can be
standardized with common pH standards.
The Lazar micro combination pH probe has also found applications in the
fields of biotechnology, biomedical research, micro chemical analysis,
