Immunity to Light Scatter Caused by Turbid Samples

“Difference spectra, ((CORM-3 plus reduced) minus reduced), of S. Typhimurium whole cells suspended in PBS were recorded in two different dual wavelength spectrophotometers. In this work, we have characterized the direct effects of CORM-3 on S. Typhimurium and demonstrate for the first time how CO released from CORM-3 binds to the terminal oxidases of the bacterium in situ in growing bacterial cultures under physiological conditions utilizing a commercial integrating cavity absorption meter (ICAM).”

“We have developed a rapid (i.e., less than 20 minutes from culture to data), virtually real-time protocol to quantitate whole-cell Hb levels in turbid suspension. Briefly, high resolution UV/Vis absorbance scans from an Olis-CLARiTY RSM-ICAM that bracket the 413-nm Soret band for hemoglobin are combined with cell numbers from an automated, impedance-based counter to generate Hb concentration values.”

“We are accumulating data on several fronts using the CLARiTY. Here is a quick slide I did for a group meeting, showing what the CLARiTY can do for dilute phytoplankton suspensions (in this case, a culture of Prochlorococcus).”
Data in the graph compares the correct spectrum collected by the OLIS CLARiTY (blue) to the nondescript spectrum collected by a Shimadzu UV-1800 (red).

There is indeed a stark difference between our Perkin Elmer spectrophotometer and the CLARiTY instrument as you will notice on the attached spectra …They were recorded in the same conditions as yours…So we are more than ever willing to have one instrument bought.”
