PinAAcle 500/900 AA Spectrometers - PerkinElmer

AA spectrometers are normally installed on laboratory work benches or tables. The benchtop or area in which the AA instrument is to be installed should be large enough to accommodate the instrument and all accessories (dimensions of those items are given in Section 10). A custom PinAAcle heavy-duty rolling bench, with locking

Hollow Cathode Lamps - Agilent

source with atomic absorption (AA) spectrometers. A single or multi-element hollow cathode lamp is required for each element to be determined using the AA technique. The key requirement for the hollow cathode lamp is to generate a narrow emission line for the element being determined. The emission line

THEORY OF XRF - Purdue University

XRF, and Chapter 4 describes how this physics is applied to spectrometers and their components. Chapter 5 explains how an XRF analysis is done. It describes the process of sample taking, measuring the sample and calculating the composition from the measurement results.

Sensitivity Versus Detection Limit - PerkinElmer

The earliest atomic absorption (AA) spectrometers provided results in terms of percent absorption (%A = 100 – %T). Those early instruments were significantly less stable than today's modern equipment, and virtually all analyses were performed with no scale expansion. For most elements, the smallest concentration

Your Essential Resource for SPECTROSCOPY SUPPLIES

• Atomic Absorption supplies that help you reduce detection limits. Our research and development efforts have also led to innovations such as single-element and solid-cathode multi-element lamps, along with high-intensity UltrAA lamps. • ICP-OES supplies that deliver reliable results for complex matrixes.

Spectroscopy: Principles, Theory, Techniques and Applications

• → Atomic absorption spectroscopy (often called AA) - This method commonly uses a pre-burner nebulizer (or nebulizing chamber) to create a sample mist and a slot-shaped burner which gives a longer pathlength flame. The temperature of the flame is low enough that the flame itself does not excite sample atoms from their ground state. The
