|10-AU-005-CE Field Fluorometer|
The 10-AU-005-CE Field Fluorometer is a rugged, field-portable instrument that can be set up for continuous-flow monitoring or discrete sample analyses. A watertight case, internal data logging, automatic range changing, watertight quick-change filter paddles, and unmatched stability make the 10-AU the instrument of choice for field studies. A variety of compounds can be easily measured on-site using application-specific optical filters available from Turner Designs.
Internal Data Logging Package. With internal data logging, up to 64,800 data points can be stored in the instrument's memory. This eliminates the inconvenience and expense associated with transporting, operating, and maintaining additional data collection equipment. Downloading data stored in the fluorometer and converting data into ASCII format is a simple process. The ASCII data can be imported directly into a standard spreadsheet program for manipulation. Using the fluorometer keypad, parameters such as the data collection interval can be selected. Also, with the addition of the temperature compensation feature, sample temperatures can be recorded.
Electronic Chart Recording Package. Graphically view the internally logged data without downloading with Electronic Chart Recording. By viewing 240 data points at a time and scrolling through the data, the user can observe trends in the field without processing the data on a computer. Internal Data Logging must be installed to use this feature.
Temperature Compensation Package (P/N 10-AU-500). Fluorescence is influenced by temperature. With increasing temperature, the fluorescence of samples and standards decreases and vice-versa. Accordingly, correcting fluorescence readings in response to temperature changes is extremely important. Environments with significant changes in temperature warrant correction of fluorescence readings for greatest accuracy. In a laboratory environment, where temperature is often controlled, temperature is usually an insignificant factor. However, in the field where significant temperature fluxuations are common, large errors in fluorometric data can result if temperature effects are ignored. Manual correction can be laborious and calculation errors can occur. Turner Designs helps customers easily correct for temperature changes by providing an optional Temperature Compensation Package for their 10-AU Field Fluorometer.
The Temperature Compensation Package includes a temperature probe that mounts onto the 25 mm flow cell (10-AU-020 or 10-AU-080) and software that automatically compensates for fluorescence changes resulting from varying sample temperature. Using the keypad, the appropriate temperature coefficient may be entered directly into the fluorometer, eliminating the need for manual correction for temperature changes.
Spreadsheet Interface Software
Turner Designs now offers Excel Spreadsheet Interface Software for the 10-AU Fluorometer. This software allows the user to directly capture data from the fluorometer to an Excel spreadsheet. This feature saves time by eliminating the middle step of transferring data from an ASCII file to an Excel file, as well as removing the possibility of transcription errors.
Part Number 10-AU-4400
Continuous-Flow Field Studies. A 10-AU equipped with the 25 mm one-piece continuous flow cell, a watertight case, internal data logging, and the 12 Volt DC Power & Signal cable is an ideal instrument for field studies. Temperature compensation is strongly recommended for dye studies. If the instrument will be transported or shipped between field sites, a transport case is recommended.
Discrete Sample Studies. A 10-AU equipped with an indoor case and the discrete sampling system for 13 mm or 25 mm test tubes allows the instrument to function well in an enclosed field setting, such as an ocean vessel research laboratory or field station.
One-Piece Flow Cell. The 25 mm One-Piece Flow Cell is easy to clean, eliminates flow cell leaks and sample compartment flooding, and simplifies calibration. Designed with a Luer lock port for injection of discrete samples into the flow cell, calibration can be accomplished quickly without switching between sample systems. For cleaning, a built-in port provides easy access to the flow cell. Flow cells of borosilicate glass or Suprasil quartz are available.
25 mm and 13 mm Cuvette Systems. The cuvette systems change easily. The 25 mm holder allows sampling with 25 x 150 mm test tubes. Simply insert the 13 mm adaptor into the 25 mm holder to accommodate 13 x 100 mm test tubes. Test tubes of borosilicate glass or Suprasil quartz are available.
10 x 10 mm Adaptor System. For applications where small sample volumes are required, the 10 x 10 mm adaptor system accommodates 10 x 10 mm square cuvettes, 100 µl vials, and 9 µl capillary tubes.
Instrument Cases. The watertight case is designed for rugged use out-of-doors and is factory-installed on the fluorometer to ensure a watertight seal. The indoor case provides protection for the instrument when used in enclosed or protected environments.
Optical Kits. Optical kits with appropriate filters and lamps are available for applications including: In vivo and extractive chlorophyll, extractive chlorophyll a (acidification or non-acidification methods), in-vivo chlorophyll a, Rhodamine WT dye, fluorescein dye, refined petroleum, and crude oil. Individual filters and lamps can be purchased as replacements or to customize the fluorometer for other applications.
Fluorometer Transport Case. To protect the fluorometer and accessories during shipment, the instrument transport case is recommended. Designed specifically for the 10-AU, it is equipped with wheels for easy maneuvering.
