Page 4: Introduction
Introduction Congratulations on your purchase of a Turner ® Spectrophotometer. Introduction SP-870 is a digital microprocessor-controlled visible spectrophotometer providing photometric read-out of Transmittance, Absorbance, Concentration and converted Factor with the following unique features. - automatic filter selection - auto zero - internal wavelength calibration - error messages - RS-232C/printer interfaces... -
Page 5: Theory
NTRODUCTION Theory A spectrophotometer is primarily used to identify unknown substances and determine their con- centrations. The following principles outline how this is accomplished. Matter absorbs energy when it interacts with an energy source such as light. Due to its distinctive atomic structure, each substance only absorbs energy between certain levels. - Page 6 NTRODUCTION transmitted. The transmittance (T) is defined as the ratio of the transmitted intensity of the light beam (I ) to the initial intensity of the light beam ), or T= I . The absorbance (A) is defined as A=log (1/T). It is found that absorbance is directly proportional to concentration: A= ε...

Page 7: Working Principle
NTRODUCTION Working Principle A spectrophotometer basically consists of five Light parts: a light source to supply electromagnetic Source energy, a monochromator to isolate the wave- length of interest and a stray light filter to elimi- nate the unwanted second order radiation, a Mono sample compartment to accommodate the chomator... -

Page 13: Operation
Operation Pre-operation check procedure Your spectrophotometer has been fully checked and aligned before shipping. However, a short pre-check should be performed before the first use of this instrument. 1. Carefully unpack your spectrophotometer and check every item against the Standard Equip- ment list. -
Page 14: Startup
PERATION Lamp for more information. Startup 1. Turn the power on. A complete initialization calibration of the instrument for electronic checks and Zero Order alignment will be automatically performed. This process will take approximately 2 minutes. The display will run through: ODEL : 1.6 AB ERSION... - Page 15 PERATION Operation procedures Turn the power on, and allow the instrument to warm up for at least 20 minutes. After an internal self-test for initializaiton calibration of the instrument is performed, the system will proceed to first memory mode automatically. The first memory mode is pre-set for wavelength at 440 nm and for Factor at 1 when the instrument is delivered.
- Page 16 PERATION 5. Zero the instrument using the blank solution by pressing the (100%T/OA) button. The display should show: TCALB ACALB then should read 100.0T 0.000A (Transmittance mode) (Absorbance mode) 6. Carefully open the sample compartment and remove the cuvette. 7. Place the cuvette with solution to be measured in the sample compartment and close the sample compartment door.

Page 17: Concentration Mode
PERATION Concentration Mode 1. Fill a cuvette with the solvent that will be used to zero the spectrophotometer. This is the blank (or background) solvent that your sample is dissolved in. 2. Place the cuvette in the cuvette holder in the sample compartment. -
Page 18: Factor Mode
PERATION 8. Select Concentration mode by pressing (C) button and key in the concentration of the Standard solution. Press the ENTER button. The display should show: XXXXX 9. Place the cuvette with unknown solution to be measured in sample compartment and close it. The display will show the Concentration of the solution immediately. - Page 19 PERATION 4. Select Transmittance or Absorbance mode by pressing the (T) or (A) button. 5. Zero the instrument using the blank solution by pressing the (100%T/OA) button. The display should show: TCALB ACALB then should read 100.0T 0.000A (Transmittance mode) (Absorbance mode) 6.
