HKL-4291 GC for Trace Ethylene Glycol in Used Engine Oil
Overview
HKL-4291 GC for Trace Ethylene Glycol in Used Engine Oil conforms to ASTM D4291 Standard Test Method for Trace Ethylene Glycol in Used Engine Oil. It is used for the measurement of ethylene glycol as a contaminant in used engine oil. The ethylene glycol is supposed to be in the range from 5 to 200 mass ppm.
The sample of oil is extracted with water and the analysis is performed on the water extract. A reproducible volume of the extract is injected into a gas chromatograph using on-column injection and the eluting compounds are detected by a flame ionization detector. The ethylene glycol peak area is determined and compared with areas obtained from the injection of freshly prepared known standards.
Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engine.
Features
A 5.7-inch large screen liquid crystal display with a 320×240 dot matrix resolution allows perfect real-time monitoring of the temperatures and operating conditions for each channel.
Automatic startup self-test, six independent temperature control channels, and seven-stage program temperature rise function.
Wide-range self-diagnosis function: Upon the occurrence of an instrument failure, it immediately displays the fault phenomenon, fault code, and fault cause, which enables you to rapidly find and fix problems and continue with optimal laboratory working condition.
Over-temperature protection function: Allows arbitrary setting of protection temperatures. If any channel exceeds the set temperature, the instrument automatically cuts off power and alarms.
Gas interruption and leakage protection function of carrier gas: The instrument will automatically stop the power and heating when the pressure of the carrier gas is too low, which makes the chromatographic column and thermal conductivity detector well protected from the damage.
An intelligent fuzzy-logic-guided rear vent system is able to monitor temperature continuously and change the vent aperture by the amount necessary, so that accurate heat control is guaranteed at a very high level of precision even in situations close to ambient conditions.
The system can handle several different ways of making injections, such as on-column injection for packed columns, glass liner injection, capillary split/splitless injection with septum purge, it is also being compatible with gas sampling accessories.
Dual-path gas stabilization ensures exceptional flow precision, allowing concurrent operation of up to four detectors.
The optimized flow architecture enables the simultaneous utilization of both a flame ionization detector (FID) and a thermal conductivity detector (TCD).
Eight programmable external event channels facilitate sophisticated multi-valve switching and sequence control.
Options include an electronic flow/pressure display module and an integrated workstation for enhanced operational convenience.
