To change the datacollection parameters for your experiment, choose Data Collection from the Experiment menu and make the necessary changes. The default settings are 1 sample per second for 200 seconds. Click to continue or click and select a wavelength on the graph or in the list of wavelengths. The wavelength of maximum absorbance will be selected as before. Click on the Configure Spectrometer Data Collection button. If you wish to store the data, select Store Latest Run from the Experiment menu. Measure an absorbance spectrum as described above.

Conduct a Kinetics Experiment (Absorbance vs.

A helper box will appear, displaying the absorbance and concentration of the unknown. Choose Interpolation Calculator from the Analyze menu. Place an unknown sample of solution in the spectrometer. Click linear fit,, to see the function for the standard solutions. After you have tested the final standard, click to end the data collection. Repeat this step for the remaining standard samples. Enter the concentration of the sample and click. Place your first Beer’s law standard solution in the spectrometer. The wavelength of the maximum absorbance will be automatically selected (λ max). Conduct a Beer’s Law Experiment (Absorbance vs. To store the spectrum data, choose Store Latest Run from the Experiment menu. Place the sample in the cuvette holder of the spectrometer and click.

#Logger pro absorbance full

Fill a cuvette about ¾ full of the solution to be tested. Calibrate the spectrometer as described above. Measure the Absorbance Spectrum of an Aqueous Sample (Absorbance vs. concentration for Beer’s law experiments, and absorbance vs. 11.3 folder, then select the olorimeter folder, and finally the Absorbance-onc file. From within Logger Pro, open the Probes & Sensors Figure 2. examine the relationship between the absorbance and concentration of a solution. a full wavelength spectrum to measure absorbance, percent transmittance. determine the wavelength (color) of maximum absorbance for a solution. wavelength which produces a spectrum, absorbance vs. Students may also connect to LabQuest 2 or to a computer with Logger Pro to. Collect Data There are three general types of data collection measuring absorbance – absorbance vs. Follow the instructions in the dialog box to complete the calibration. Calibrate the Spectrometer for Measuring Absorbance or %T With the spectrometer connected to your computer and Logger Pro 3 running, choose Calibrate ► Spectrometer from the Experiment menu. Macintosh computers (Mac OS 10.3 or newer) If it appears, follow the New Device instructions.

#Logger pro absorbance drivers

Windows computers (Windows XP or Vista) Follow the New Hardware Wizard instructions to download the drivers automatically. The device drivers were installed when you installed Logger Pro 3. Note: Do not go online for device drivers. The first time you connect a spectrometer, your computer may ask you a few questions. Allow the spectrometer to warm up for a few minutes. Connect the spectrometer to a powered USB port or a powered hub.

#Logger pro absorbance install

Install Logger Pro 3 software (version 3.6 or newer) on your computer before using an Ocean Optics spectrometer. Visit Get Started Using a Spectrometer with Your Computer 1. You need the LabQuest application version 1.1 or newer to use a LabQuest as a stand-alone device with a spectrometer.

#Logger pro absorbance upgrade

If you own a previous version of Logger Pro 3, you may upgrade the software free of charge.
