SECTION 1 - Introduction INSTRUMENT DESCRIPTION The SP-200-UV spectrophotometer is suited to a wide range of applications in education, quality control, environmental and clinical analysis. This model is a UV/visible spectrophotometer covering a wavelength range from 198nm to 1000nm, with measurement modes for absorbance, % transmittance and concentration.
SECTION 2 – Installation UNPACKING Remove the SP-200-UV from the packaging and ensure the following items are included: 1. Model SP-200-UV spectrophotometer 2. Required power cable either UK mains lead moulded plug (HH179(S)), EU mains lead moulded plug (HH180(S)), or US mains lead moulded plug (FCABLEUS) 3.

SECTION 3 – Theory and Practice of Spectroscopy Measurements THEORY OF SPECTROSCOPY MEASUREMENT UV-visible spectroscopy is the measurement of the absorbance of light at a specific wavelength in a sample. This is used to identify the presence and concentration of molecular entities within the sample.
The optical layout of the SP-200-UV spectrophotometer is shown below: Figure 3.2.1 – Diagram of light path The light from the xenon lamp is focused onto the grating, with 1200 lines per millimeter, which separates the light into discreet wavelengths.
GOOD PRACTICE GUIDELINES 1. For optimum performance all spectrophotometers should be sited in a clean, dry, dust free atmosphere. When in use ambient temperature and light levels should remain as constant as possible. 2. If required adherence to Standard Operating Procedures (SOP) and Good Laboratory Practice (GLP) should be monitored with regular calibration checks and a suitable Quality Control (QC) programme.

h) Flow-through cuvettes must be selected with care and consideration for the sample type, sample volume, pumping system, rinse, sample and waste handling to be used. 5. Samples and standards should not be stored in open cuvettes or sample containers as evaporation will change the value and lead to staining of the walls which may be irreversible.
SECTION 4 – PHOTOMETRICS MEASUREMENTS The SP-200-UV can perform simple measurements of % transmittance or absorbance. The sample is measured at one wavelength and at one point in time. TRANSMISSION MEASUREMENT MODE To select % Transmittance use the LEFT or RIGHT arrow keys to move the cursor to the %T indicator on the menu bar (refer to figure 2.3.1).
SECTION 5 – CONCENTRATION MEASUREMENTS The concentration measurement mode enables simple measurements of concentration to be performed. In this measurement mode it is possible to calibrate against a standard of a known concentration or use a known factor. The sample is measured at one wavelength at one point in time.
The sample number is incremented every time the PRINT key is pressed. The following commands can also be sent to the SP-200-UV via the serial interface (using Windows HyperTerminal, for example): ASCII D or d Same as pressing the PRINT key ASCII T<CR>...

SECTION 8 – Maintenance and Service ROUTINE MAINTENANCE Ensure the external surfaces of the unit are clean and free from dust. The sample area should always be kept clean and any accidental spillage should be wiped away immediately. To give added protection when not in use, the unit should be disconnected from the mains supply and covered with the optional dust cover.

Scientific Help (refer to section 9.2). Error Code Error Name Issue This error occurs when the SP-200-UV closes the shutter to Err 1 Dark cal error block light entering the sample chamber. If the detector output does not fall to a level normally associated with a dark cal then this error is indicated.
This product meets the applicable CE Directives that interference will not occur in practise. Where and UKCA Legislation for radio frequency there is a possibility that injury, damage or loss might interference and may be expected not to occur if equipment malfunctions due to radio interfere with, or be affected by, other equipment with similar frequency interference, or for general advise before qualifications.
