Introduction
A petroleum existent gum tester is an instrument used to measure the existent gum content of the gasoline and the aviation fuels, which is the non-volatile residue formed during the evaporation, and it is used in the petroleum, the fuel, and the quality control industries. The existent gum is measured by the evaporation of a specified volume of the fuel under the controlled conditions, and the weighing of the residue, and it indicates the tendency of the fuel to form the deposits in the engine and the fuel system, following the standard test methods, such as the ASTM standards; the petroleum existent gum tester consists of an evaporation bath or the block, a temperature control system, the glassware for the sample, an air or a steam supply, and the accessories, and it provides the existent gum content, expressed in milligrams per 100 milliliters, with features such as the temperature control; the petroleum existent gum tester is used for the measurement of the existent gum in the gasoline and the aviation fuels, for the quality control, for the assessment of the fuel stability, for the compliance with the specifications, and for many other applications, and it is an essential instrument for the fuel testing. Petroleum existent gum testers are used in the petroleum industry, in the fuel industry, in the laboratories, in the quality control, and for many other applications. With their existent gum measurement, petroleum existent gum testers are essential for the fuel quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum existent gum tester is used in petroleum refineries, fuel quality laboratories and third-party testing organizations to measure the existent gum content of aviation gasoline and motor gasoline. It supports fuel specification compliance, refinery process control, storage stability evaluation and product certification. Existent gum indicates the amount of non-volatile residue formed by oxidation and polymerization of unstable hydrocarbons in gasoline during storage and use. High gum content can cause intake valve deposits, carburetor fouling and engine performance problems. The jet evaporation method provides a standardized measurement that is essential for ensuring gasoline quality, particularly for aviation fuel where gum content is strictly regulated for flight safety.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D381 for existent gum in fuels by jet evaporation, ISO 6246 for petroleum products gum content, and the corresponding GB/T 8019 method. The instrument complies with relevant laboratory electrical and gas safety standards. Evaporation temperature and air flow should follow the standard specification.
Q3: What is the warranty period for the whole machine and key components?
A: The bath, flow controller and heating system are covered by a 12-month warranty. Evaporation beakers and tubing are consumables excluded from warranty. Damage from improper air flow, overheating or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with the test method and gravimetric analysis. We provide an operation manual and remote guidance. Proper beaker preparation, sample volume, evaporation conditions and cooling procedure are critical for accurate gum content measurement.
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: Bath temperature calibration against a reference thermometer is recommended every 6-12 months. Air or steam flow should be verified periodically with a calibrated flow meter. Balance calibration should follow the laboratory quality system. Full method verification with a reference fuel is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Evaporation beakers, tubing and filters are available from laboratory suppliers, though beaker dimensions should match the standard method. Air or steam supply should meet the method purity and flow requirements. Long-term consumable cost is moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes number of test positions, bath capacity and flow control type. Additional beaker sets 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 instrument, beakers and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of samples are compatible with this equipment?
A: The tester handles aviation gasoline and motor gasoline within the method gum content range. Samples should be representative and free of particulate contamination. Highly volatile samples require careful handling to prevent loss of light ends before testing. Users should follow the standard method for sample handling, evaporation conditions and gravimetric measurement, including proper beaker weighing technique and cooling in a desiccator.
