Oil and grease analyzer

Introduction

An oil and grease analyzer is an instrument used to determine the concentration of oil and grease in water, wastewater, soil, and other samples, and it is used in environmental monitoring, wastewater treatment, industry, and food processing for compliance testing and pollution control. Oil and grease is a measure of the total amount of petroleum hydrocarbons, animal and vegetable fats, and other hydrophobic substances in the sample, and it is analyzed by extracting the oil and grease from the sample with a solvent, such as hexane, and measuring the amount extracted; the analysis is performed by gravimetric methods, in which the solvent is evaporated and the residue is weighed, or by infrared spectroscopy, in which the infrared absorbance of the extract is measured, or by fluorescence and other methods, and the analyzers may be automated, following standard methods, such as EPA Method 1664, and the results are expressed in milligrams per liter or milligrams per kilogram. Oil and grease analyzers are used for monitoring the oil and grease in wastewater discharges, for compliance with discharge permits, for monitoring oil pollution in surface water and groundwater, for monitoring industrial process water, for testing food processing wastewater, for monitoring the quality of water in the petroleum industry, for soil analysis, and for many other applications, and they are available as portable extraction instruments and benchtop analyzers, with features such as automated extraction, precise measurement, and data analysis. With their measurement of oil and grease, oil and grease analyzers are essential for environmental monitoring and compliance testing.

FAQ

Q1: What testing scenarios is this analyzer mainly applied to?

A: The oil and grease analyzer is used in environmental monitoring, wastewater treatment, industrial facilities, food and beverage, petroleum and research to measure the oil and grease (total petroleum hydrocarbons, fats, oils and greases) content in water and wastewater for regulatory compliance, environmental monitoring and process control. It supports wastewater effluent oil and grease monitoring for discharge compliance, industrial process water oil content monitoring, environmental water quality assessment (rivers, lakes, groundwater), food processing wastewater monitoring, petroleum industry water testing, and stormwater monitoring. Oil and grease is a common regulated pollutant in wastewater, making its measurement essential for environmental compliance and treatment process optimization.

Q2: What standards does the analyzer comply with?

A: The oil and grease analyzer follows relevant ISO, ASTM and GB/T standards for oil and grease measurement, including EPA Method 1664 (n-hexane extractable material), ASTM D3921, ISO 9377-2, and relevant GB/T standards including GB/T 16488 (infrared method) and HJ 637 (gravimetric). The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified reference materials (e.g., certified oil standards) traceable to international standards. Wastewater discharge limits follow applicable regulations (GB 8978, local discharge standards).

Q3: What is the warranty period for the whole machine and key components?

A: The whole oil and grease analyzer is covered by a 12-month warranty. The extraction system, measurement unit, controller and housing are covered, while glassware, solvents, filters and fuses are consumables or accessories. Damage from improper use, solvent spills or unauthorized repair is excluded. Extended service contracts may be available.

Q4: Is this device difficult to operate? Is professional training required?

A: Operation requires trained laboratory personnel familiar with oil and grease testing, solvent extraction and chemical safety. We provide operation manuals, training and application support. Proper sample collection and preservation, solvent extraction, evaporation, measurement, calibration and safety procedures (flammable solvents) are important for accurate results and safe operation.

Q5: What is the typical lead-time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is regular calibration required? What is the recommended calibration cycle?

A: Calibration with certified oil standards recommended every 6-12 months (for infrared method). Routine verification with a control sample per batch. Glassware condition checked. Solvent purity verified. Full system performance verification annually. Routine cleaning of extraction and measurement system.

Q7: Are supporting consumables universal?

A: Solvents (n-hexane, perchloroethylene, Freon substitute), filters, glassware, sodium sulfate and reference materials are available from laboratory suppliers, though instrument-specific parts should be verified. Long-term consumable cost is moderate depending on sample volume and solvent usage.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes measurement method (gravimetric, infrared, UV), sample capacity, automation level, solvent type, data output and accessories. Additional glassware and accessories can be ordered separately. Custom orders extend delivery lead-time.

Q9: Does the purchase include on-site installation and commissioning service?

A: Standard delivery includes the oil and grease analyzer and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged at additional cost. Remote guidance is provided. Fume hood is required for solvent extraction.

Q10: What types of samples are compatible with this equipment?

A: The oil and grease analyzer measures oil and grease content in wastewater, surface water, groundwater, process water and other aqueous samples within the method range and sample specification. Samples should be collected in glass containers (not plastic, as oil adheres to plastic), preserved with acid (pH <2) and refrigerated per standard methods. Different methods (gravimetric, infrared) have different detection limits and requirements. Users should follow the specific test method (EPA 1664, HJ 637, GB/T 16488) for sample collection, preservation, extraction, measurement and reporting, use proper solvents (n-hexane for gravimetric, perchloroethylene or substitute for infrared), include method blanks and matrix spikes for quality control, report results in mg/L with method specified, and for regulatory compliance, follow applicable discharge standards. The extraction should be performed in a fume hood due to flammable/toxic solvents. Glassware should be properly cleaned (rinsed with solvent) to prevent cross-contamination. Sodium sulfate (drying agent) should be properly baked before use. For samples with high suspended solids, proper filtration or acidification may be required. Waste solvents should be disposed of per hazardous waste regulations. The sample should be analyzed within the holding time (typically 28 days for oil and grease when properly preserved).
