Carbonyl Sampling

About Our Comprehensive Line of Carbonyl Sample Collection Products
Supelco LpDNPH cartridges are manufactured to the highest quality standards in a low background carbonyl-controlled manufacturing environment. We offer the widest range of carbonyl sampling devices in the Air Monitoring market with 7 different packed cartridge configurations and 18 products. We also offer our innovative radial passive sampling devices, Radiello® and DSD-DNPH; LpDNPH coated filters; and other adsorbents for sampling carbonyls. Select LpDNPH products are vacuum packaged in our low-background storage bag. Our products are suitable for OSHA, NIOSH, ASTM, EPA, CARB methods.

Low Concentration Environment, <20 µg/carbonyls
ORBO-DNPH Tube – The ORBO-DNPH tube contains a single bed of 120mg of 2,4-DNPH packed into a glass tube with a “frangible” break seal at both ends, each tube measuring 6 mm O.D. x 90 mm long

Typical Sampling Environment, 20 – 75 µg/carbonyls
ORBO-555 and ORBO-558 LpDNPH Tubes – both contain two beds packed with high purity LpDNPH with a front bed of 300-mg and a back-up bed of 150-mg. (NIOSH 2016 Appendix B). The ORBO-555 is a 6 mm O.D. glass tube suitable for sampling at lower flow ranges up to 0.4 L/min, and the ORBO-558 is an 8 mm O.D. glass tube which extends the flowrate range up to 2.0 L/min.
 
S10 Cartridge – This design makes the S10 cartridge easy to use in the field and the laboratory. Reusable adaptors are available for connecting the cartridge to the sampling pump. The built-in reservoir eliminates the need to attach to a syringe for sample extraction/elution. All S10 cartridges are 3 mL in size and are composed of our low extractable polypropylene syringe barrel packed with 350 mg of LpDNPH.
 
S10L Cartridge – The S10L cartridge offers a reversible design and is for analysts who prefer shorter dimensions and do not need an adaptor for sampling. The cartridge is eluted by connecting to a syringe barrel that acts as a reservoir for gravity-fed elution solvent. Meets EPA TO-11A requirements
 
S10x Cartridge – The S10x cartridge is shorter than the S10 cartridge and designed to fit automated systems.
 
Rezorian™ DNPH Cartridge – Rezorian cartridges are made of low extractable polypropylene with polyethylene frits. The end-fittings are luer lock syringe connections that can be used individually or connected in a series (piggybacked) to monitor breakthrough or to increase capacity.
 
BPE-DNPH Cartridge – This innovative product is packed into our Rezorian cartridge and is dual-layered and designed to enable the end-user to use the front BPE (1,2-bis(2-pyridyl) ethylene (BPE)) on silica gel bed as an inline ozone scrubber and measure aldehydes in the same tube. This product is also not affected by high humidity.

High Capacity Sampling Cartridges: LpDNPH H-Series
The H-series of LpDNPH cartridges contain higher loadings of 2,4-DNPH and larger bed weights compared to the S10 cartridges. This provides a much higher capacity for carbonyls making the H-series cartridges the preferred choice for use in high concentration environments. The H-series is available in H10 (350mg), H30 (1g) and H300 (10g) cartridges
Capacity: 75-225 µg/carbonyls
H10 – Same configuration as our S10 cartridge but with a higher loading capacity. It is packed with 350 mg of high capacity LpDNPH in a 3 mL syringe barrel.
 
Capacity: 225 – 643 µg/carbonyls
H30 – Contains 1 g of high capacity LpDNPH packed into a 6-mL syringe barrel.
 

Capacity: 643 µg – 6.4 mg/carbonyls
H300
– Is our highest capacity carbonyl sampling cartridge packed with 10 g of high capacity of LpDNPH into a 20 mL syringe barrel.

Ozone Scrubbers
We offer two configurations for the potassium iodide ozone scrubber in a reversible design- like the S10L cartridge, and a Rezorian style cartridge both versions contain 1.5 g of high purity potassium iodide.

Ozone Capacity: 100,000 ppb/hr
Potassium Iodide (KI) Scrubbers – We offer two configurations for the potassium iodide ozone scrubber in a reversible design- like the S10L cartridge, and a Rezorian style cartridge both versions contain 1.5 g of high purity potassium iodide Testing (200 ppb ozone, 50% RH, 25 ºC)
