Page 4: Introduction
The TD-550 is ideal for the analysis of produced water samples where crude oil concentrations can vary from low levels to over one thousand parts-per-million. The dual channel TD-560 offers the TD-550’s functionality in the NUV channel, as well as a deep ultraviolet (DUV) channel, which provides the extreme sensitivity required to monitor very low hydrocarbon concentrations and detect weakly fluorescent hydrocarbons, such as some gas ... -
Page 5: Specifications
TD-550/560 Oil in Water Analyzer Introduction The TD-550/560 must be operating in the linear range to display accurate results. To determine whether your calibration standard is in the linear range, first, select the NUV or DUV channel (TD-560) and proper cuvette size and calibrate the analyzer with a standard solution of known concentration. (See Section 3 General Considerations for Analysis for configuration guidelines.) Then prepare a new ... -

Page 11: Channel Selection Guidelines
TD-550/560 Oil in Water Analyzer Operation CHANNEL SELECTION GUIDELINES The TD-550 is a single-channel crude oil analyzer with extended range and low detection limits for most crude oils. The TD-560 features two channels. The near ultraviolet (NUV) channel, provides the same functionality as the TD-550. In addition, the deep ultraviolet (DUV) channel can be used where high sensitivity is required. The DUV channel can detect all of the commonly used refined oils, crude oil, and gas condensates, with significant improvement over competing analyzers. The DUV channel is ideal for weakly fluorescent hydrocarbons or for very low concentrations of hydrocarbons. NUV Channel (TD-550/560) In most cases, use the NUV channel for measuring •... -
Page 12: Calibration Overview
TD-550/560 Oil in Water Analyzer CALIBRATION OVERVIEW Before the TD-550/560 can be used to analyze a sample, you must calibrate it with a blank and a calibration standard containing your target hydrocarbon. If you are following a solvent-extraction method, use the pure extraction solvent for the blank. Prepare the calibration standard by dissolving a known amount of hydrocarbon in a known volume of extraction solvent. -

Page 14: General Information And Precautions
• The TD-550/560 is very sensitive and even small amounts of material from a previous sample may result in errors. Use a clean cuvette for each reading. Wipe the outside of the cuvette with a Kimwipe or similar laboratory tissue. Do not use paper towels or kitchen wipes because the optical brighteners in the paper may cause a false reading. -

Section 4.2, and Section 4.3, respectively. IMPORTANT NOTE REGARDING SOLVENTS Some solvents, especially Vertrel MCA, Ashikleen AK-225, and chloroform, can damage the TD-550/560 if left in contact with the plastic parts. If you spill solvents on the case or inside the sample well, flush the contacted area immediately with isopropyl alcohol and dry the area with a non-abrasive lab tissue. - Page 16 Analysis Method TD-550/560 Oil in Water Analyzer Part 2—Preparing a Calibration Standard The following table values apply to a 10:1 (water to oil) extraction ratio. Select a concentration that is equal to the maximum anticipated in your water samples. Prepare a Calibration Standard by diluting the Stock Standard with clean solvent. Recipes for preparing several typical concentrations are given in Table 1.

NOTE: If you have not calibrated the analyzer, follow the calibration procedure in Section 5 No- Solvent Analysis Method. 11. If applicable, select a saved location from the Locations list (2), or tap New to create a location. 12. Tap Read (3). A new reading is stored in the Reading History screen. 13. If measuring an unknown sample, you should always check for linearity as discussed in Section 6 Troubleshooting. - Page 20 Analysis Method TD-550/560 Oil in Water Analyzer NOTE: If you are using lighter than water extraction solvent then refer to Section 4.2 of this manual for lighter than water extraction solvent analysis procedure. NOTE: The following procedure describes a 10:1 water to oil extraction ratio. If a different extraction ratio is used, the volumes of water sample and/or extraction solvent will be different.

NOTE: If you have not calibrated the analyzer, follow the calibration procedure in Section 5 No- Solvent Analysis Method. 15. If applicable, select a saved location from the Locations list (2), or tap New to create a location. 16. Tap Read (3). A new reading is stored in the Reading History screen. 17. Check that the fluorescence response is at least 200 fluorescence units greater than the blank. Calibrations with fluorescence response differences less than 200 indicate insufficient sensitivity. If this occurs, consult Section 6 Troubleshooting.

Page 22: Solvent Analysis Method
EQUIPMENT NEEDED The No-Solvent Method requires a TD-550/560 Oil-in-Water Analyzer and auxiliary equipment available from Benchmark International. Other common laboratory items can be purchased from a variety of sources (e.g., VWR International, LLC, www.vwr.com). To prepare for calibration Label four (4) clean, dry sample bottles 1000 ppm, BLANK, BKG (WSO), and OIW. - Page 23 TD-550/560 Oil in Water Analyzer No-Solvent Analysis Method To prepare the 1000 ppm standard Place 3 mL of OIW Surfactant into the bottle marked 1000 ppm. Pipette 100 µL of oil directly into the OIW Surfactant. Swirl the bottle until the oil is fully dispersed in the OIW Surfactant.
- Page 24 No-Solvent Analysis Method TD-550/560 Oil in Water Analyzer On the Create Calibration screen, tap the Name field (1) and enter a name for your calibration. Tap the Password field (2) and enter your password. Tap Save (3). The Calibration screen appears. On the Calibration screen, choose Near UV from the drop-down menu (TD-560 only). NOTE: The Deep UV channel is not compatible with the No Solvent Method because of surfactant interference. You will not be able to save calibrations conducted by the No Solvent Method when the Deep UV channel is selected.
