UPW-OB100 Portable Fully Automatic Infrared Oil Content Analyzer

Product Introduction
The UPW-OB100 Portable Fully Automatic Infrared Oil Content Analyzer is designed for measuring total oil, petroleum hydrocarbons, and animal and vegetable oils in a wide range of water samples. Suitable for surface water, groundwater, industrial wastewater, domestic sewage, seawater, aquaculture water, and agricultural irrigation water, it can also be used to determine oil content in cooking fumes from the catering industry.
The instrument integrates sample volume measurement, demulsification, solvent extraction, water removal, infrared detection, data storage, and result printing into an automated workflow. Its non-contact sample volume measurement system automatically reads the water sample volume and adds the appropriate extraction solvent, minimizing sample transfers and helping reduce oil loss during preparation.
Featuring a rugged, portable carrying-case design, the UPW-OB100 is suitable for laboratory use and field testing in vehicle-mounted, mobile, and marine environments. It supports full-spectrum scanning, three-wavenumber measurement, and single-point non-dispersive infrared analysis, providing flexible measurement options for different testing requirements.
Additional features include automatic magnesium silicate column switching, extraction solvent purity monitoring, multiple calibration methods, adjustable sample volumes and extraction ratios, and an integrated printer. These capabilities make the UPW-OB100 a practical solution for environmental monitoring, wastewater testing, and industrial oil-content analysis.

Performance Features
1. Fully Automated Analysis: Automatically performs demulsification, solvent extraction, water removal, infrared measurement, data storage, and other routine analytical operations.
2. Portable and Rugged Construction: Uses a waterproof, shock-resistant, heat-resistant, and corrosion-resistant carrying case for mobile testing and demanding field environments.
3. Automatic Sample Volume Measurement: Measures water sample volume without contact, automatically calculates the required extraction solvent addition, and transfers the sample directly into the extraction process.
4. Three Oil Measurements in One Workflow: Supports determination of total oil, petroleum hydrocarbons, and animal and vegetable oils within an integrated analytical workflow, subject to the selected method and required sample treatment.
5. Automatic Magnesium Silicate Column Switching: Monitors the remaining magnesium silicate capacity, provides a reserve column position, and can automatically switch to the backup column when the primary column requires replacement.
6. Integrated Oil-Water Separation: A specialized separator removes water and impurities without requiring sodium sulfate desiccant filling or membrane replacement.
7. Automatic Solvent Purity Monitoring: Evaluates extraction solvent purity and provides an alarm when solvent replacement is required.
8. Flexible Sample Preparation: Allows users to configure sample volume and extraction ratio for samples with different oil concentrations.
9. Three Infrared Measurement Modes: Offers full-spectrum scanning, three-wavenumber measurement, and single-point non-dispersive infrared measurement.
10. Multiple Calibration Options: Supports three-standard correction, standard-curve calibration, and single-point calibration to accommodate different analytical workflows.
11. Real-Time Result Printing: Includes an embedded printer for immediate output of measurement results and testing records.
12. Flexible Touchscreen or Tablet Operation: Provides a dedicated tablet mounting position, allowing users to operate the instrument with a handheld tablet or mount it directly on the analyzer.

Working Principle
The UPW-OB100 uses infrared absorption spectroscopy to determine oil concentrations after extracting oil compounds from the sample into an appropriate solvent.
The analytical process consists of the following stages:
1. Automatic Sample Volume Measurement: The instrument measures the volume of the water sample without direct contact and calculates the required extraction solvent volume.
2. Demulsification and Solvent Extraction: The sample undergoes automated pretreatment to separate oil compounds from the aqueous phase and transfer them into the extraction solvent.
3. Water and Impurity Removal: The integrated oil-water separator removes residual water and impurities from the extract. The instrument also uses a magnesium silicate column where required for the selected oil determination method.
4. Infrared Measurement: The prepared extract is analyzed using one of three modes: full-spectrum scanning, three-wavenumber measurement, or single-point non-dispersive infrared measurement.
5. Concentration Calculation: The instrument processes the infrared absorption signal using the selected calibration method and accounts for the sample volume and extraction ratio to determine the oil concentration.
6. Data Storage and Reporting: The result is stored electronically and can be printed immediately using the built-in printer.
The automated workflow reduces manual sample handling, improves operational convenience, and supports repeatable oil-content analysis. The exact target fraction and applicable analytical standard depend on the selected measurement method and sample preparation procedure.

Technical note: The original source lists the wavenumber range using “px⁻¹,” which is not a standard spectroscopic unit. The table interprets this as cm⁻¹ converted to m⁻¹ based on the stated wavelength equivalents. Confirm the manufacturer's intended units and the stated minimum detection concentration before publishing the final technical specification.
