The linear photometric range is from –2,000 to +2,000 units of absorbance. There is possibility of storing up to 1000 data points and 50 user calibration graphs. Also the spectrophotometer can be connected with a computer or a printer for the transfer of the data. Reagents for the determination of the concentration of phenols, cloride ions, nitrates, ammonium ions, total phosphorus and potassium ions were purchased which are specially adjusted for determinations with the spectrophotometer. 

13. System for the determination of anaerobic and aerobic metabolism of microorganisms in soil and in aquatic solutions.

All the equipment was purchased from Acualytic company. The methods which are used are based on the determination of the relative pressure due to the anaerobic or aerobic respiration where exhange of gases takes place. The determinations are made with the help of electronic sensors of pressure (electronic manometers, model Sensor-IR) which are screwed on the measurement bottles. These sensors accept and send out the pressure data through infra-red radiation to a mobile controller, model Sensomat-Scientific AL350. The data can be stored in this controller, or they can be sent to the computer or to the printer with the appropriate cable and programme which are included.

A. System for the determination of the biological oxygen demand concentration (BOD):

The system is consisted of 12 dark BOD bottles of 500 ml, 12 pressure sensors (Sensor-IR), an magnetic stirring base for 12 BOD bottles (model AL322) and a thermostatically controlled cabinet (model AL185) of 180l volume and temperature adjustment range from 4 to 40 ˚C. The cabinet and the pressure sensors are also used from the systems described below.

B. System for the analysis of aerobic and anaerobic metabolism:

The system consists of 6 bottles DURAN GL45/25 of 1000 ml, a magnetic stirring base for 6 bottles (model AL353). At the anaerobic metabolism it is possible to quantify the produced biogas and the substrate conversion. Furthermore many other results can be optained such as the toxicity of the substrate, the efficiency of fermenters, the optimum conditions of cultivation. The same results can be optained at the analyses of aerobic metabolism. Process successions from aerobic to anaerobic or vice versa can also be quantified.

C. System for the analysis of microbial respiration of the soil (and other substates):

Τhis system consists of 6 bottles (Measurement Vessels) of 1000 ml, a magnetic stirring base for 6 bottles (model AL353). The method is the same with the analysis of aerobic metabolism reported in the previous paragraph, the only difference is that different kind of bottles are used. Here also various results can be optained such as the respiration of microorganisms (and bigger organisms, e.g. worms) which are fed with the substrate (e.g. soil, compost, sludge), the biodegradability testing of substances (pesticides, fertilizers, chemicals), the toxicity of substances.
