SilcoCan air sampling tank (Silanized Suma tank)

The ideal choice for analyzing low levels of inactive sulfur (5-20ppb), TO-14A, and TO-15 compounds.

The matching Siltek processing tank and Siltek valve have over inertness and can handle sulfur compounds or bromine compounds.

High quality 2/3 stainless steel diaphragm interface with metal to metal sealing is used to prevent sample adsorption and ensure more accurate analysis results.

The sampling tank and valve are made of 304 and 316 stainless steel materials to withstand the harsh tests of field work.

Optional 2-way or 3-way valve; Three way valve link 30 "Hg/60psi vacuum/pressure gauge (other instruments)

Long service life, no loss, easy operation, new RAVE valve.

Use humidified air, with a high temperature of 80 degrees Celsius; Use inert gases such as nitrogen, with a pressure gauge at 120 degrees and without a pressure gauge at 140 degrees, for cleaning the sampling tank.

In order to achieve good overall inertness, the SilcoCan atmospheric sampling tank adopts Restek's unique Siltek processing technology. It is easy to collect and store even highly active compounds with a concentration of one billionth without loss. The RAVE valve has high quality and adopts a metal sealing ring and a 2/3 stainless steel diaphragm for the steering valve, which can prevent sample absorption and obtain more accurate results. The material is divided into stainless steel and Siltek treated RAVE valves, with specifications available in two-way and three-way. Each sampling tank must be slightly pressurized with non polluting nitrogen before leaving the factory.

Whether you are monitoring T O-1 4 A, T O - 1 5 , The inertness of S i l coCa n tanks or sulfur-containing compounds is your best choice. In the Tedlar sampling package, even within 24 hours, the stability of low-level volatile sulfur organic compounds (VOCs) is poor. Sulfur compounds undergo electrolytic reactions with the metal surface of the tank. So these tanks are not suitable for collecting and storing volatile organic compounds with low sulfur content. The SilcoCan air sampling tank features special Siltek surface treatment technology, which provides excellent storage stability for very low levels (5-20 ppbv) of sulfur-containing volatile organic compounds under dry or humid conditions. The versatility of SilcoCan tanks makes it the best choice for collecting and storing TO-14 or TO-15 compounds.

Typical cleaning methods:

1. Connect the canisters to the cleaning system, release any pressure within any of them, and evacuate them. Based on EPA Method TO-15, the ultimate vacuum achieved during cleaning should always be<0.2 mm Hg.

2. After the canisters have been under vacuum for approximately 1 hour, pressurize them with humidified nitrogen to 5 psig (0.34 bar) (if they will be heated during cleaning) or to 30 psig (2.0 bar) (if they will not be heated). Caution: If heat is used during cleaning, use humidified nitrogen only—do not use air. Cleaning SilcoCan canisters with humidified air and heat above 80 °C may damage the fused silica surface, resulting in reduced recoveries of sulfur and other reactive compounds. Pressurization will dilute the contaminants and the water vapor will hydrolyze them. When the system has equilibrated at the designated pressure, proceed to step 3 (heating), or step 4 (no heat).

3. Heat the pressurized canisters to the appropriate temperature. A Restek SilcoCan canister fitted with a gauge can be heated to 120 °C; a canister without a gauge can be heated to140 °C.**

Note: These temperature limits only apply using an inert gas like nitrogen. If using air, all SilcoCan canisters must be cleaned at 80 °C or below.

4. Allow the canisters to equilibrate for at least 1 hour. Evacuate the canisters to remove the impurities, then allow them to equilibrate for 1 hour.

Repeat steps 2–4 as necessary. The number of cycles will be determined by how dirty the canisters are and how easily they clean. Without heat, the number of cycles required to clean the canisters may be higher.
