Conclusion

Today's PCRs on AMO and Nir were successful when DMSO was added.

Lab 115

Main purpose

Run Experiment 2. E.coli control measurement.

Who was in the lab

Ariadni, Natalia

Procedure

Adjusting the temperature at 37<up>o</sup> and calibrating the probes as described in Appendix 5.

Following the protocol Experiment 2

Changing the steps :

19. Add 0.5 ml of nitrite solution and continue by adding 0.5 ml after 10 minutes.

We added 0.5 ml nitrite again and then we took 2 ml of sample, we added then 0.5 ml and afterwards when there was any change in the curve we spiked with 0.4 ml of nitrite. We took 2 ml for sample in the end and we added 0.5 ml of N2O and 1 ml of NO to see if the probes are working properly.

Results

Colorimetric results

Measurements of standard solutions

Ammonium - 43.7 mg/L ( expected 39 mg/L)

Nitrite - < 2 mg/L (X10 diluted) -0.4 mg/L (with no dilution) (expected 0.5 mg/L)

Nitrate - 18.7 mg/L (X10 diluted) (expected 12 mg/L)


Measurement of samples


Ammonium

Measuring range 2-75 mg/L NH4-N

start point- no signal

middle point- signal <2 mg/L

end point- signal 0.7 mg/L


Nitrate

Measuring range 1-25 mg/L NO3-N

start point- no signal

middle point- signal <1 mg/L

end point- signal <1 mg/L


Nitrite

Measuring range 0.02-1 mg/L NO2-N

start point- no signal

middle point- signal 0.43 mg/L

end point- signal 0.79 mg/L

Conclusion

Problems with the NO probe and there were not proper results.
