The VWR Scientific 710-0949 SAS Pinocchio Air Sampler Contact Plates are essential components for using the Pinocchio Sampler, a versatile and innovative instrument designed for the analysis of volatile organic compounds (VOCs) in ambient air. These contact plates are engineered to provide optimal surface area for the adsorption of VOCs during the sampling process.
The contact plates are made of porous sorbent material, specifically Tenax TA, which is widely recognized for its high capacity and selectivity in trapping VOCs. Each plate measures 2 inches in diameter and 1/16 inch thick, offering an active adsorption area of approximately 14 square inches. This large surface area increases the efficiency of the sampling process, allowing for the collection of a greater volume of VOCs.
The plates are designed with a radial flow configuration, which ensures uniform distribution of the adsorbed VOCs during desorption. This configuration also minimizes the risk of cross-contamination between samples, as each plate serves as an independent adsorbent. The radial flow design also simplifies the sample preparation process, as the desorption solvent can be easily introduced from the edge of the plate.
The contact plates are designed to be disposable, ensuring that each analysis is conducted with fresh, uncontaminated adsorbent material. They are also compatible with a wide range of desorption solvents, such as dichloromethane, methanol, and carbon disulfide, making them versatile for various analytical techniques.
In summary, the VWR Scientific 710-0949 SAS Pinocchio Air Sampler Contact Plates are an essential accessory for efficient and accurate VOC analysis using the Pinocchio Sampler. Their large surface area, radial flow configuration, and compatibility with various desorption solvents make them an indispensable tool for environmental and industrial applications.
VWR Scientific's 710-0949 SAS Pinocchio Air Sampler Contact Plates are used in the SAS (Solid-Adsorbent Sampler) method for the collection of airborne particles. Here are some pros and cons of buying these contact plates:
Pros:1. High Collection Efficiency: These contact plates have a high collection efficiency for particles in the size range of 0.3 m to 10 m. This makes them suitable for use in various industries such as pharmaceuticals, food, and beverage, where particle contamination needs to be monitored and controlled.
2. Compatibility: These contact plates are compatible with the VWR Scientific SAS Pinocchio Air Sampler, making them a convenient choice for users of this particular sampler.
3. Reusable: These contact plates can be reused multiple times, making them a cost-effective option for frequent air sampling needs.
4. Easy to Use: The contact plates are easy to install and remove from the sampler, and they come pre-coated with a thin layer of adsorbent material, eliminating the need for users to apply the adsorbent themselves.
Cons:1. Limited Particle Size Range: While these contact plates have a high collection efficiency for particles in the size range of 0.3 m to 10 m, they may not be suitable for collecting particles outside of this range.
2. Requires Special Handling: The contact plates need to be handled carefully to avoid contamination and ensure accurate results. They should be stored in a clean environment and handled using clean gloves.
3. Limited Shelf Life: The contact plates have a limited shelf life and should be used within 12 months of the date of manufacture to ensure accurate results.
Conclusion:The VWR Scientific 710-0949 SAS Pinocchio Air Sampler Contact Plates are a good choice for users of the VWR Scientific SAS Pinocchio Air Sampler who need to collect airborne particles in the size range of 0.3 m to 10 m. Their high collection efficiency, compatibility with the sampler, reusability, and ease of use make them a convenient and cost-effective option for frequent air sampling needs. However, their limited particle size range, requirement for special handling, and limited shelf life are potential drawbacks that should be considered before making a purchase.
Recommendation:If you require the collection of airborne particles outside of the size range of 0.3 m to 10 m, or if you need a longer shelf life for your contact plates, you may want to consider other types of air sampling media or contact plates from different manufacturers. However, if you only need to collect particles within the specified size range and are comfortable with the handling and shelf life requirements, then the VWR Scientific 710-0949 SAS Pinocchio Air Sampler Contact Plates are a good choice.
