Original Quartz Ametek Insert Spark Stand SpectroMaxx Part No 48207006/48207008/48207009/48207013

Original Quartz Ametek Insert Spark Stand SpectroMaxx Part

As a spectrometer accessory, the “Quartz Insert Spark Stand” most commonly refers to the quartz rectangular tube or its key replaceable components (such as the center tube) used in the SPECTRO ICP-OES spectrometer.
It is a key consumable in the ICP light source generation device, and its performance and state directly affect the stability of the plasma, instrument sensitivity, background noise, and long-term stability.
The exact part number and specifications of the quartz sheath/rectangular tube that are suitable need to be determined based on the specific model of the SPECTRO spectrometer. The design of the rectangular tube used in different models of ICP spectrometers (such as SPECTRO ARCOS, SPECTROBREE, SPECTRROGREEN, etc.) may vary.
1. Spark:
Refers to SPECTRO Analytical Instruments GmbH (Spark Analytical Instruments GmbH, Germany). It is a leading global manufacturer of spectral analysis instruments, particularly well-known in the field of atomic emission spectroscopy such as ICP-OES. Now it belongs to the Material Analysis Department of Ametec Group.
2. Spectrometer accessories:
It has been clarified that this’ quartz sheath ‘is used as a component or consumable part of the spectrometer.
3. Quartz sheath:
In Spark spectrometers (especially ICP-OES), the core component of this “quartz sheath” refers to the quartz rectangular tube or its constituent parts.
ICP rectangular tube: It is one of the core components of inductively coupled plasma spectrometer. Sample aerosols, plasma gas (argon), and cooling gas are mixed here and induced by high-frequency coils to generate high-temperature plasma (up to 6000-10000K).
Why quartz?
Ultra high temperature resistance: Quartz is one of the few materials that can withstand the extreme high temperatures of ICP plasma for a long time.
Chemical inertness: High purity quartz has excellent resistance to most sample matrices and strong acid environments, avoiding contamination of the sample or corrosion of itself.
Optical transparency: For spectrometers that require lateral observation of plasma (which is the design of many models of Spark), the rectangular tube needs to be transparent in order to collect the light signal emitted by the plasma through the optical path.
Good thermal stability: low thermal expansion coefficient, reducing the risk of thermal stress rupture.
4. Specific form (meaning “sheath”):
The entire quartz rectangular tube: the most common understanding. It is itself a component made of quartz with a specific structure and channel (central tube, outer tube, middle tube), which wraps and guides the airflow to form plasma.
Replacement parts/inner tubes of rectangular tubes: In some designs, the “sheath” may specifically refer to the part of the rectangular tube that is susceptible to sample aerosol erosion (such as the inner tube or nozzle of the central tube), which needs to be replaced more frequently as a consumable, while the outer tube may have a longer lifespan.
Protective sleeve/shielding tube: In a few specific designs or applications, it may also refer to a quartz protective tube that is placed outside the core component (such as the central injection tube) to isolate high-temperature plasma or reduce deposition.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.

As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
