Description
Torch Active Flow Hitachi SPS-3000/7800 Series
Part Number:
40072008109C
Cross Reference(s)
40072008109C
Instrument Compatibility:
Seiko / Hitachi SPS-3000/7800 Series
Torch Detail:
Quartz, torch is a specific torch component designed for Hitachi Inductively Coupled Plasma (ICP) spectrometers, such as the SPS3500 and 7800 series. It is a critical part of the sample introduction system, where the plasma is formed and maintained for elemental analysis
What makes the Active Flow Hitachi Torch better?
- Function: It is designed to maintain a stable argon plasma for elemental analysis, specifically optimized for “active flow” to handle complex sample matrices with high stability.
- Design: These torches typically feature a quartz or ceramic body with specific dimensions for gas flow (coolant, auxiliary, and nebulizer gas) to ensure efficient excitation of sample atoms.
- Applications: Primarily used for trace element analysis in environmental, food, and industrial samples where high sensitivity and matrix tolerance are required
Key Specifications & Compatibility
- Instrument Compatibility: Primarily used in Hitachi High-Tech (formerly Seiko) ICP-OES and ICP-MS systems, including the SPS3000 and 7800 series.
- Design Type: Often categorized as a “High TDS” (Total Dissolved Solids) torch, meaning it is engineered to handle samples with high salt content or complex matrices without frequent clogging.
- Material: Constructed from high-purity quartz
Typical Maintenance & Usage
- Function: The torch consists of concentric quartz tubes that manage argon gas flows (coolant, auxiliary, and nebulizer) to sustain the plasma and carry the sample.
- Cleaning: Regular cleaning is required to prevent “memory effects” or sensitivity loss, especially when running high-matrix samples.
- Replacement: The torch is a consumable; common reasons for replacement include devitrification (whitening) of the quartz, physical damage, or persistent contamination
