• Increasing Productivity and Simplifying Sample Preparation with the SIPS accessory Technical Overview Flame Atomic Absorption Spectrometry (FAAS) typically involves element-specific sample preparation which can be time consuming and prone to operator-introduced errors. The SIPS 10 and SIPS 20 Sample Introduction Pump System (SIPS) are optional accessories for Agilent's SpectrAA FAAS instruments. They offer a range of powerful features that automate many tedious and error prone sample preparation tasks. These greatly simplify and speed up the sample preparation process, improving productivity and reducing costs. The combination of the SIPS and Agilent's Fast Sequential capabilities results in an easy to use, highly productive and cost effective Atomic Absorption solution.

Whether you are using an autosampler, or doing manual sample introduction, a SIPS accessory, combined with the SpectrAA software, will automatically: • Prepare up to 10 calibration standards from a single bulk standard, automating the instrument calibration process • Intelligently dilute over range samples • Prepare standard additions calibration from a single standard • Introduce analytical spikes, using a single standard • Add chemical modifiers, e.g. ionization suppressants • Extend the dynamic range of FAAS to that approaching ICP-OES The SIPS accessory is available in two versions: • The...

The SIPS 20 comprises two pumps (Figure 2). One delivers the sample and the second delivers a standard or modifier to the nebulizer. Controlling the relative speeds of both pumps allows the amount of standard or modifier added to the sample to be precisely regulated. This allows in-line 'spiking' of samples. No More Tedious Standard preparation The SIPS 10 and 20 are capable of preparing calibration standards from a single multi-element bulk standard. This reduces sample preparation time and the risk of operator error during standard preparation, which can lead to costly re-runs. Using the concentration...

Modifier addition Flame AA methods routinely require the addition of chemical modifiers for accurate results. These modifiers are normally added during the sample preparation process. Using the second pump of the SIPS 20, modifiers can be automatically added during the analysis, taking a repetitive step out of the sample preparation process. The amount of modifier added is controlled by the pump speed, and this pump speed remains constant during sample dilutions to ensure consistent blank correction and matrix modification; something that must be accounted for when adding modifiers manually. In-line...
