HKL-1945 GC for Analysis of Natural Gas
Overview
HKL-1945 GC for Analysis of Natural Gas conforms to ASTM D1945 Standard Test Method for Analysis of Natural Gas by Gas Chromatography. It can analyze the chemical composition of natural gases and similar gaseous mixtures.
Components in a representative sample are physically separated by gas chromatography (GC) and compared to calibration data obtained under identical operating conditions from a reference standard mixture of known composition. The numerous heavy-end components of a sample can be grouped into irregular peaks by reversing the direction of the carrier gas through the column at such time as to group the heavy ends either as C5 and heavier, C6 and heavier, or C7 and heavier. The makeup of the sample is determined through a comparison of peak heights, peak areas, or a combination of both with the respective values gotten from the standard reference.
Features
With a 5.7-inch LCD display and 320×240 dot matrix, the large screen clearly shows real-time temperature and ALL channel operation parameters, thereby enabling comprehensive online monitoring.
The device executes an automatic self-diagnostic on its powering up, features six separate temperature zones that can be individually controlled, and allows seven-stage programmable temperature ramping.
Outfitted with a very broad self-diagnostic feature, the system can automatically present fault descriptions, error codes, and most likely causes in plain language whenever a breakdown happens.
Moreover, there is an adjustable over-temperature protection which allows the setting of safety limits for each channel. When the temperature of a zone goes beyond the preset limit, the device will not only cut off power but also warn with an alarm.
The equipment has built-in carrier gas failure protection to avoid the damage of essential parts. If the gas pressure is lower than the necessary level, it will disconnect the power and stop the heating process. This way, it will prevent the chromatographic column and thermal conductivity detector from being harmed.
An intelligently controlled rear vent system, based on fuzzy logic, keeps checking the internal temperature all the time and adjusts the vent opening in a natural way. As a result, temperature is very well controlled, even when the operation is close to the conditions of the surrounding.
These are packed column on-column injection, glass liner injection, and capillary split/splitless injection devices with septum purge function, as well as support for installing gas samplers.
Dual stabilized gas flow paths with high precision allow up to four detectors to be installed at the same time.
An advanced gas flow design makes it possible to use the hydrogen flame ionization detector and the thermal conductivity detector at the same time.
Eight external event functions support multi-valve switching.
Options include an electronic flow or pressure display system and a built-in workstation device.

FAQ
Q1: What standards does this product (HKL-1945 GC for Analysis of Natural Gas) comply with?
A:HKL-1945 GC for Analysis of Natural Gas conforms to ASTM D1945 Standard Test Method for Analysis of Natural Gas by Gas Chromatography. It is capable of determining the chemical composition of natural gases and other related gas mixtures. The components of the sample are first separated physically by gas chromatography (GC), then the results are matched with calibration data from a reference standard mixture of known composition that was obtained under the same operating conditions. The numerous heavy-end components of a sample can be grouped into irregular peaks by reversing the direction of the carrier gas through the column at such time as to group the heavy ends either as C5 and heavier, C6 and heavier, or C7 and heavier. The composition of the sample is calculated by comparing either the peak heights, or the peak areas, or both, with the corresponding values obtained with the reference standard.
Q2: What is the applicable scope of HKL-1945 GC for Analysis of Natural Gas?
A: This test method covers the determination ofthe chemi-cal composition of natural gases and similar gaseous mixtures within the range of composition. This testmethod may be abbreviated for the analysis of lean natural gases containing negligible amounts of hexanes and higher hydrocarbons, or for the determination of one or more components, as required. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
