Autosampler Trays and Probes for ICP

What is the Autosampler Trays and Probes for ICP?

Autosampler trays and probes hold sample vials and transfer solutions in routine ICP sequences. They are replacement and expansion parts that determine capacity, carry-over, durability and compatibility with aggressive samples, and they wear with use.

Overview

A tray positions vials relative to the sampler arm, and the probe dips into each vial to draw sample, standard or rinse solution. Trays are available in different capacities, typically 60 to 240 positions, and in cooled versions for volatile standards or temperature-sensitive samples. Probe material matters: standard polymer probes suit aqueous acids, while inert PFA or ceramic probes are used for hydrofluoric acid, and some probes have level sensing. Probe depth, wall thickness and tip geometry affect carry-over and the ability to reach low liquid volumes. Rinse stations may be single or double. Trays, probes and rinse cups are consumable and must be replaced when cracked, contaminated or when carry-over rises.

How does it work?

The plasma and sample path are exposed to high temperature, acid fumes and salt deposits, so their components are consumables that wear, corrode or become contaminated. Quartz torches and injectors shape the plasma and must be replaced when they devitrify, crack or accumulate deposits that change sensitivity. Nebulizers and spray chambers set aerosol quality and transport efficiency. RF load coils and torch boxes deliver the plasma power and must be matched to the generator and torch. Peristaltic pump tubing controls sample flow and internal standard addition, and worn tubing changes volumes. Autosampler probes, trays and rinse stations determine carry-over and throughput. Using the correct part number and material for each instrument, element and matrix, and replacing parts on schedule, protects sensitivity, precision and safety.

What are the key features?

• Trays with 60 to 240 vial positions
• Cooled trays for volatile standards
• Standard, inert PFA or ceramic probes
• Level sensing probe options
• Single or double rinse stations
• Probe geometry optimized for low carry-over

What are the technical specifications?

A typical autosampler trays and probes for icp configuration offers tray capacity of 60–240 vials, vial volume of 10–60 mL, probe material of PTFE, PFA, ceramic or quartz, probe outer diameter of 1.0–3.0 mm, minimum sample volume of 0.5–2 mL and cooling option of 4–10 °C. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Autosampler Trays and Probes for ICP is used in expanding autosampler capacity, inert probes for hydrofluoric acid samples, cooled trays for volatile standards and replacement of worn or contaminated probes. Across the wider ICP Accessories class, laboratories also deploy it for replacement torches and injectors for plasma systems, nebulizer and spray chamber maintenance kits and RF coil and torch box service parts.

Which standards and certifications apply?

Relevant standards and methods include USP <730> Plasma Spectrochemistry, USP <1058> Analytical Instrument Qualification, ISO 11885 Water quality — ICP-OES determination of elements, ISO 17294-2 Water quality — ICP-MS determination of elements, IEC 61010-1 and ISO/IEC 17025. Certification candidates for this model are CE, ISO 9001 manufacturing and Material cleanliness certification; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Accessory condition is the most common reason for drifting sensitivity, noisy baselines and failed quality checks. Establish a maintenance schedule based on sample load and matrix: inspect torches and injectors for deposits and cracks, clean or replace nebulizers when uptake falls, and replace pump tubing and probes at defined intervals. Keep spares of the parts most likely to fail, because a blocked nebulizer or cracked torch stops the laboratory. Handle quartz carefully, store it clean and dry, and never use abrasive tools on injectors or nebulizers. After any replacement, verify performance with a check standard, confirm plasma stability and update the instrument log with the part and date.

How do I select the right Autosampler Trays and Probes for ICP?

Select trays and probes by instrument model and sample needs. Choose cooled trays if standards are volatile or samples degrade, and inert probes for hydrofluoric acid or ultratrace work. Confirm tray capacity matches your throughput and that probe geometry can reach your minimum sample volume without introducing air.

How does it compare with other ICP Accessories variants?

Select accessories by exact instrument model, torch type and application. Quartz torches are standard for aqueous and many organic methods, while ceramic or inert torches suit hydrofluoric acid and high-purity work. Injector bore diameter affects aerosol velocity and plasma stability, so match it to the sample introduction system and matrix. Nebulizers range from concentric for clean solutions to V-groove or parallel-path for high solids. Spray chambers differ in transport efficiency and washout time. RF coils and torch boxes must match the generator frequency and power. Pump tubing is chosen by internal diameter and chemical resistance. Autosampler probes and trays must fit the sampler. Confirm part numbers, materials and availability of performance data before ordering.
