HKL-8440 FTIR Spectrometer for total recoverable petroleum hydrocarbons
Overview
HKL-8440 FTIR Spectrometer for total recoverable petroleum hydrocarbons conforms to the EPA Method 8440 Total Recoverable Petroleum Hydrocarbons by Infrared Spectrophotometry. This standard is used for the measurement of total recoverable petroleum hydrocarbons (TRPHs) extracted with supercritical carbon dioxide from sediment, soil and sludge samples. It is not applicable to the measurement of gasoline and other volatile petroleum fractions, because of evaporative losses.
Soil samples are extracted with supercritical carbon dioxide. Interferences are removed with silica gel, either by shaking the extract with loose silica gel, or by passing it through a silica gel solid-phase extraction cartridge. Following infrared (IR) analysis of the extract, TRPHs were quantitatively analyzed through direct comparison with standards.
Features
Highly Stable Optical System: An integrated design and one-piece molding process have been adopted for this optical platform, which facilitates precise positioning of the main components by means of only one single alignment procedure and there is no need of adjustments afterwards. This greatly improves the stability of the instrument and totally solves the issue of maintenance of traditional optical structures, which is a big problem.
Advanced Electronic Architecture: The system features a latest 24-bit A/D converter with a sampling rate of 500 kHz. A highly sensitive imported infrared detector is used to acquire real-time spectral data at the highest precision and reliability. Transferring data has become much faster due to the introduction of USB 2.0 communication interface, enabling the whole sample analysis to be done in seconds.
Intelligent Humidity Management System: Equipped with a sealed interferometer and continuous humidity monitoring, this spectrometer drastically lessens the reliance on the manual user interventions. A visual, color-changing indicator that is very intuitive lets you know when the desiccant needs to be changed, thus preventing one of the main risks in FTIR operation. Changing the desiccant is fast and easy, and you don't even have to take the instrument apart.
Integrated Corner Reflector Technology: It uses one piece of gold-plated reflector only that has been used in both dynamic and static optical systems. It has been designed to reach maximum light throughput and highest reflectivity. Since there is no glue used, such a structure is resistant to change in the surrounding temperature and has high stability.
Core components imported from the Developed countries in Europe and America; Light source, detector, beam splitter, die: All these major components are imported from the Western countries. The quality is guaranteed as those imported components are top-notch.

FAQ
Q1: Which standards are met by a HKL-8440 FTIR Spectrometer for total recoverable petroleum hydrocarbons?
A: HKL-8440 FTIR Spectrometer for total recoverable petroleum hydrocarbons conforms to the EPA Method 8440 Total Recoverable Petroleum Hydrocarbons by Infrared Spectrophotometry. Soil samples are extracted with supercritical carbon dioxide. Interferences are removed with silica gel, either by shaking the extract with loose silica gel, or by passing it through a silica gel solid-phase extraction cartridge. After infrared (IR) analysis of the extract, TRPHs are quantitated by direct comparison with standards.
Q2: Scope of application?
A: This instrument is used as a referee method for determining both the interstitial oxygen content in double-side polished silicon slices and the substitutional carbon concentration in single crystal silicon. It is essential for materials acceptance, fabrication process control, and research and development.
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.
Q4: Are there discounts for bulk purchases/wholesale?
A: Yes, we offer highly competitive tiered pricing and bulk purchase incentives for customers with volume procurement needs (such as university centralized procurement, complete laboratory setups, OEM manufacturing, and channel distributors).
Q5: How is their safety ensured during transportation?
A: We have a professional instrument packaging team that uses customized shock-absorbing foam boxes and reinforced wooden crates. We also partner with logistics providers who specialize in precision instrument transportation to ensure that the goods are delivered to you safely and without damage.
