C400e Nebulizer

The Savillex C-Flow 400e (C400e) PFA concentric nebulizer combines the reliability of a low flow glass concentric nebulizer with the chemical resistance and low elemental background of a PFA concentric nebulizer. In addition, its unique constant diameter capillary gives the C400e excellent resistance to clogging.

The C400e body has an ESI type thread to allow direct connection to the ESI FAST discrete sampling system used with ICPMS.

While microconcentric (uptake rate 200μL/min or less) PFA nebulizers are used as standard with ICP-MS for semiconductor applications, most non-semiconductor ICP-MS labs use low flow glass nebulizers due to their more suitable uptake rate and relatively low cost. The Savillex C400e was designed specifically for non-semiconductor ICP-MS use and while it can free aspirate, it is designed to be pumped and is optimized for the typical uptake rates (350-400μL/min) of today’s ICP-MS systems.

Moulded from high purity virgin PFA, the C400e offers the chemical resistance and low metal background of a conventional PFA nebulizer, but with several unique features. Its two-piece precision moulded design allows precise optimization of back pressure during manufacture, ensuring consistently high performance. It also features an inner body that supports the capillary all the way to the tip, making it more robust and giving it a longer lifetime compared to other PFA nebulizers.

The C400e is optimised for use at 1SLPM to match the carrier gas flow rates of all common ICP-MS, and it’s 6 mm OD body fits all common spray chamber end caps.

The C400e is also extremely resistant to clogging by particulates: inside the nebulizer body, a constant ID capillary avoids the changes in ID that cause potential blockage points. And because the capillary is supported at the tip, the C400e can be easily and safely backflushed – without the need for tools.

The C400e is capable of handling over 15% total dissolved solids (TDS). The C400e connects directly to all of the ESI FAST uptake line connectors for reliable, reproducible connections and the fastest possible washout. A threaded PFA gas inlet fitting ensures a reliable, leakfree carrier gas connection and includes a range of adapters to connect to common gas line sizes. Like all Savillex nebulizers, the C400e is designed, moulded and assembled by Savillex, and its design has enabled a significant reduction in assembly time and subsequent price reduction. As a result, the C400e offers all the benefits of PFA nebulizers at a price comparable to low flow glass nebulizers.

Combining high performance and ruggedness with fast washout, high matrix tolerance, chemical inertness and long lifetime, at an excellent price point, the C400e is the perfect choice for any ICP-MS equipped with the ESI FAST.

Note: For the routine, non-semicon ICP-MS use, without ESI FAST, choose the C400d, which is the same nebulizer as the C400e, but with a removable 80 cm uptake line and a Savillex zero dead volume connection. The Savillex uptake line cannot be used with the C400e since thread fittings are different.
