H2S (Hydrogen Sulfide) Calibration Standard
|
| Methylene blue concentrate that, once diluted 1:50, provides the same absorbance value of hydrogen sulfide at 665 nm at a concentration of 1.145 μg·ml-1 sulfide ions. This concentration value is the highest absorbance value with the linear range of the spectrophotometer and can be used as the stock solution to prepare standards for the calibration curve. It is suitable for preparing 50 calibration curves using the recipe described in the table. The standard is stable for at least one year. |

Aldehyde Calibration Standard
|
The Aldehyde Calibration Standard consists of nine 2,4-dinitrophenylhydrazones (2,4-DNPH) diluted in 10 mL acetonitrile. Certified concentrations of each compound are described in the table. Actual concentrations are certified for each lot. The standard stock solution is shipped in a pierceable-septum crimped cap vial, and is stable for at least 4 months when stored in the dark at 4°C. |

| radiello Calibration kits |
 |
The kits consist of twelve cartridge adsorbents (Cat. No. RAD130 or RAD145). Three of which are blanks and nine preloaded, divided into three concentration groups. Concentrations are described in the listed tables. The values shown are indicative. Actual concentrations are certified for each lot. The cartridges are stable for at least four months when stored at 4°C. |
BTEX Calibration Kit (CS2 Desorption)
|
| The BTEX Calibration Kit (CS2 Desorption) is designed for the analysis of BTEX in urban environments. The kit may be used for both routine calibration and quality control. The kit consists of twelve Code 130 Cartridge Adsorbents (Cat. No. RAD130). The BTEX preloaded simulate 7 day exposures (100,080 minutes). |

BTEX Calibration Kit (Thermal Desorption)
|
| The BTEX Calibration Kit (thermal desorption) was designed for the analysis of BTEX in urban environments followed by thermal desorption. The kit may be used for both routine calibration and quality control. The kit consists Code 145 Cartridge Adsorbents (Cat. No. RAD145). The BTEX preloaded simulate 7 day exposures (100,080 minutes). BTEX is spiked on the cartridges by injecting vaporized BTEX standards in methanol under nitrogen flow. A methanol peak may be visible during chromatographic analysis. |

VOCs Calibration Kit (Workplace Environment)
|
The VOC Calibration Kit is ideal for conducting scheduled quality control runs when analyzing workplace environments. The kit consists of Code 130 Cartridge Adsorbents (Cat. No. RAD130).
Three of which are blanks and nine, divided into three concentration groups, are preloaded with VOCs to simulate 8 hour exposures (480 minutes). The composition of VOCs represents a broad range of polarity, and the spiked concentrations represent 0.5, 1.0, and 2.0 times the threshold limit values (TLV) for each compound. VOCs are spiked on the cartridges by injecting vaporized VOC standards in CS2 under nitrogen flow. |
