Exploring the differences between Titan 2 and competing technology, Gas Chromatography (GC)
When detecting benzene, Titan 2 has advantages over all other technologies. Titan 2’s closest competition is Gas Chromatography (GC). In this article, we explore the benefits of Titan 2 over gas chromatography for benzene detection.
Technology Principles
Gas Chromatography is a method used in analytical chemistry to separate and analyze compounds, commonly benzene, as well as other VOCs. It is very useful for the separation, identification, and quantification of compounds, as well as purity analysis of samples, and particularly useful when detecting benzene due to the volatility of the compound.
Titan 2 utilizes Micro Gas Chromatography and is accompanied by a PID to offer detection of benzene at very low levels. Micro GC is a miniaturized version of conventional gas chromatography, featuring smaller column sizes, faster analysis times, and lower power requirements. Combining Micro GC with PID technology offers high sensitivity as well as rapid and sensitive analysis, resulting in a versatile and powerful analytical tool.
Sample Time
Typically, a gas chromatograph is situated at a central point and is linked to several sampling lines that are switched in via a valve block, and then each line is tested sequentially. Despite the GC system claiming to offer continuous detection, it took the GC we tested an entire hour to scan all of its input lines. Titan 2, however, takes samples every 60 seconds. When we performed comparative product testing, it was evident from the data that there were instances where the GC completely failed to detect entire events, unlike Titan 2, which successfully captured these events.
Operating Environment
Environmental conditions for gas chromatographs to operate effectively are required to be stable, meaning they are often used in a clean or controlled environment such as a lab or controlled area. The device’s accuracy and reliability may be hindered if external factors like temperature and humidity are not monitored and controlled. Specifically, it is crucial that humidity levels do not surpass 80% relative humidity (non-condensing).
Titan 2 can be easily installed and commissioned in the detection area, with the IP65 rated enclosure offering reliable protection against the intrusion of dust and water. Titan 2 is able to operate in conditions with up to 99% relative humidity (non-condensing). The ruggedness of Titan 2 guarantees continued functionality in demanding environments, including areas with significant amounts of dust and humidity.
Upfront and Ongoing Costs
Gas Chromatography: Gas Chromatographs alone cost upwards of $35,000, although this is for the most basic functionalities. Additional features are typically required, dependent upon application, thus increasing the price even further to approximately $60,000 or more. This upfront cost doesn’t take into consideration the required ongoing costs, including:
Gas supply
GCs require an inert carrier gas to pass the sample gas through the device. The most commonly used carrier gases used in GCs are helium, nitrogen, and hydrogen, although this often depends on the specific requirements of the analysis. These gases are not a one-time cost and need to be replaced periodically.
Maintenance
This includes costs for routine cleaning, calibration, and inspection of the GC machine. Parts such as the injection port liners, seals, and the column itself may need replacement over time, depending on usage.
Service and maintenance
Similarly to Titan 2, GC suppliers offer service contracts that cover annual maintenance and emergency repairs. Uniquely, it is recommended that GC devices are thoroughly cleaned as frequently as possible, which can take up a lot of time, although it is imperative that they are regularly cleaned otherwise the quality of that data outputted by the GC will degrade.
Software licences
Some GC systems require proprietary software for data analysis, which can have licensing costs. There may also be ongoing costs for software updates and support. In addition to this, downtime due to software installation can lead to omission of entire events.
Consumables
These include syringes, vials, septa, and other items that are used in the running of the GC which are required to be replaced regularly.
Titan 2: Titan 2’s initial price comes in near 20k. This price, even combined with 5 years of maintenance, is still significantly less than buying a fully equipped GC unit alone.The minimal maintenance required for Titan 2 includes:
Consumables
Consumable replacement parts are included within the 6 and 12 month maintenance kits, where local service centers are fully trained by our service technicians to replace these parts. This reinforces Titan 2’s reputation of being low-maintenance, while giving customers assurance that they are receiving the best post-sales support from their local service center.
Gas Supply
Titan 2 should be regularly bump tested and calibrated with a small test cylinder of gas. Although there isn’t a ‘one size fits all’ answer for how regularly it should be calibrated, we recommend bump testing every 1-2 weeks, if not more often, and calibrating every 2-4 weeks, however this will be dependent upon the application.
Servicing
Titan 2 should be serviced every 6 months, application dependent. With this in mind, ION Science offer 6 month and 12 month maintenance kits. The Titan 2 maintenance kits contain all of the required replacement parts for your Titan 2 instrument after continued use, from filters to sensors, to ensure that Titan 2 is performing at its optimum level. Both 6 and 12 month maintenance kits are supplied through our global authorized service centers as part of their industry-leading post-sales support.
Sensitivity
With VOC exposure limits becoming increasingly regulated, it is imperative that technologies available on the market are able to successfully and accurately detect down to the required lower levels. Current GCs on the market are able to detect benzene down to parts per billion (ppb) levels, much like Titan 2 – but for a fraction of the price.
Titan 2 utilizes our enhanced AirSep filter which allows for fast and accurate benzene detection. Titan 2’s sensitivity complies with upcoming EU benzene exposure limit changes and showcases ION Science’s continued reputation of staying ahead of the curve with any new product.
Summary
When it comes to a cost effective, reliable solution for benzene monitoring, the benefits of opting for Titan 2 over other technologies are indisputable. ION Science also offers up to 2 years of warranty on all Titan 2 instruments when they are registered on the ION Science website, peace of mind is guaranteed with our premium technology.
