BBE
ALGAE TOXIMETER
|
The
bbe Algae Toximeter provides continuous toxicity measurement
based changes in the fluorescence spectrum and fluorescence
kinetics of the algae. Statistically significant deviations
in algae fluorescence activate an alarm. |

How
it works
The bbe Algae Toximeter continually determines toxic substances
in water. For the tests, algae are automatically and independently
cultivated. These standardised algae are added to the water sample
and the active chlorophyll concentration is analysed. If the algae
are damaged, e.g. through herbicides which reduce activity (e.g.
indirectly the oxygen evolution) of the algae, an alarm is induced.
The new and advanced bbe Algae Toximeter works with shorter measuring
intervals and a PC for an online data analysis, which realises
a higher temporal resolution of the monitored water.The instrument
has got an automatic cleaning device and a userfriendly interface.
Advantages of the bbe Algae Toximeter
-
high sensitivity concerning the recognition of herbicides
and their by-products
- independent
cultivation of algae
- cultivation
control due to the active chlorophyll measurement
- no
dosage mistake through ageing tubes
- automatic
cleaning of the measuring unit
- no
loss of time through the alarm induction
- auto-start
after current failure
- battery-buffered
for data saving

Application |
|
|
bbe Toximeters
provide a highly sensitive biological system for early detection
of potentially dangerous unknown substances, in a wide variety
of circumstances. These instruments are ideal for detecting water
quality contamination in real-time to protect both plant and animal
life. The Toximeters provide a means to detect (and alert users
to) potentially dangerous circumstances. Based on the alert, the
user may then take appropriate measures including further chemical
analysis, water source diversion, process suspension or further
treatment. Expensive chemical analysis can be targeted to key
toxic events with potentially significant cost savings. Some examples
of applications for our Toximeters include:
- environmental
monitoring, including ports, lakes, reservoirs and dams
- source/ground
water monitoring, supply monitoring and intake monitoring
- surface
water monitoring including rivers and lakes, measuring stations
and early warning systems
- pre-treatment
assessment
- post-treatment
quality control
