CIA Advantage - The next generation of automated canister analyser
CIA Advantage - the key benefits for canister users
Economy and productivity
- No need for liquid cryogen means savings of thousands of dollars per annum per instrument
- Up to 27 channels allows round-the-clock automated operation for maximum productivity
- Heated internal lines (up to 200°C) and uniquely efficient purging combine to eliminate carryover. This means fewer blanks and more samples, allowing you to generate higher revenue
- High- and low-concentration samples can be accommodated in the same sequence. Prescreening of uncharacterised samples can be carried out automatically with no need for dedicated equipment
- Robust modular design optimises uptime and enhances serviceability, thus minimising maintenance costs
- Easy water management
- Peerless analytical performance, including splitless desorption for optimum sensitivity
- Simple but sophisticated, single-stage trapping with an optimised combination of sorbents and electrical cooling provides the ultimate VOC pre-concentration capability. Even ultra-volatiles and polar species can be quantitatively retained, while interferents such as CO2 and water are selectively eliminated
Flexible and future-proof
- Electronic splitting capability and the option of small-volume sampling via gas-loop further enhance compatibility with high-concentration samples. This eliminates the need for time-consuming sample preparation steps such as canister dilution
- Compatible with both canister/bag analysis and method-compliant analysis of sorbent tubes, allowing you to satisfy a wider range of applications, such as TO-17 air toxics, SVOCs and passive sampling
The CIA Advantage range
Overview of operation
Metered by gas loop or mass flow controller, each air/gas sample is introduced directly into the electrically-cooled, sorbent-packed focusing trap. Sorbents and trapping temperatures are optimised for retention of organic components and simple/effective elimination of water and CO2. The trap then heats rapidly in a reverse stream of carrier gas to transfer the retained compounds into the analytical system. This transfer can be performed splitless for maximum sensitivity.
Flow path heating to 200°C and uniquely effective line purging between samples eliminates carryover. This minimises the requirement for blanks and boosts productivity.
Detection limits: <0.1 ppb (1 L sample, quad full scan)
<10 ppt (1 L sample, quad SIM mode)
Carryover: Typically <0.2 ng absolute (<0.04%)
Precision: Target air toxic compounds: typically 1–10% RSD
Internal standards: 1–4% RSD
Linear conc. range: Up to 5 orders of magnitude, harnessing split versatility
Full compliance with US EPA Method TO-14/15
Monitoring the volatile organic hazardous air pollutants specified in US EPA Method TO-14/15 for air toxics is a key canister application. CIA Advantage offers full compatibility with this method, while providing the productivity and analytical excellence that comes as standard with all Markes systems.
Routine TO-14/15 analysis benefits hugely from the peerless analytical performance of the CIA Advantage coupled with low-cost, cryogen-free operation. Internal standard addition capability is included as standard for optimum reproducibility.
Negligible carryover and the inherent concentration flexibility of the CIA Advantage also mean that ambient air samples can be directly calibrated with small volumes of relatively inexpensive higher-concentration standards if required. (Alternatively, Markes’ diluter can be used to generate low-level standards from ppm-level calibration gases.)
Highly efficient trapping and desorption, even under splitless conditions, makes for optimum sensitivity and resolution. This enhances identification of target analytes, even at trace levels and against the most complex backgrounds.
For a system to be capable of analysing samples covering a wide concentration range within a single sequence, it must have exceptionally low sample carryover. By combining a heated lowvolume flow path (operating to up 200°C) and stringent purging steps, the CIA Advantage completely eliminates the risk of analyte condensation and carryover.
Uniquely efficient trapping
High-performance analysis of highly volatile hydrocarbons is straightforward with the CIA Advantage. The efficient design of the UNITY 2 focusing trap, integrated into every CIA Advantage system, even allows quantitative retention of acetylene using sample volumes up to 1.5 L. Moreover, Markes’ technology achieves this without the need for liquid cryogen.
Flexible and future-proof
Wide concentration range
Gas loop and mass flow control sampling options accommodate sample volumes ranging from 0.5 mL to 1 L (depending on the canister size and which CIA Advantage model is chosen).
Negligible carryover and electronically-controlled sample splitting further enhance the dynamic range, allowing both high- and low-concentration samples to be analysed in the same sequence without the need for dilution. Excellent linearity is obtained across the range.
Sorbent tubes complement canisters, offering compatibility with SVOCs as well as conventional VOC air toxics. Tube desorption capability also facilitates passive sampling for unobtrusive personal monitoring and cost-effective deployment of large numbers of samplers during major field studies. Every CIA Advantage offers Markes’ world-leading manual tube desorption capability featuring SecureTD-Q™ – quantitative sample re-collection for repeat analysis. Tube desorption can also be fully automated, allowing you to adapt your CIA Advantage to any future requirement.
Maximum volatility range
The design and efficiency of the electrically-cooled UNITY 2 focusing trap, integrated into every CIA Advantage system, gives optimum performance for the widest possible range of analytes. Ultra-volatile species such as freons and C2 hydrocarbons can be analysed quantitatively, together with the highest-boiling compounds that can be reliably recovered from canisters or ambient-temperature air/gas streams.
Suitable for fixed and mobile laboratories
Cryogen-free operation means the CIA Advantage is ideal for installation in unattended field monitoring stations (on-line mode) or mobile labs, as well as the traditional laboratory environment.
Economy and productivity
No liquid cryogen
The efficient electrically-cooled trapping used in the CIA Advantage eliminates many of the costs and complexities associated with cryo-cooled systems. This means no topping-up with coolant, fewer interruptions to automated sequences, and simplified water management. Electrical cooling is also fully compliant with US EPA Methods TO-15 and TO-17.
With up to 27 channels available, the CIA Advantage allows round-the-clock operation. In addition, a range of sample volumes and widely differing concentrations can be accommodated in the same sequence. This increases the efficiency of workflow and means that uncharacterised samples can be prescreened automatically with no need for dedicated equipment.
Sample integrity – no cross-contamination
Heated internal lines (up to 200°C) and uniquely efficient purging combine to eliminate carryover. This means fewer blanks and more samples, allowing you to generate higher revenue. Even two fewer blanks per day could result in an extra $400, generating up to $100,000 extra income every year (based on a 5- day working week).
Advanced water management
The CIA Advantage deals effectively with even the most humid of samples. Selective purging of water, sophisticated sample splitting and optional in-line dryers reduce water accumulation and maximise up-time. Other air interferences such as CO2 are also selectively purged before analysis.
Easy maintenance and high uptime
The robust modular design of the CIA Advantage minimises maintenance costs and maximises uptime. Systems are backed-up by Markes’ experienced technical support team, and feature advanced functions for sample security. Internal standard addition and an integrated leak test ensure quantitative sample transfer and reliable data time after time.
