Niton™ Apollo™ 手持式 LIBS 分析器

<p>Yes, Niton Apollo Handheld LIBS Analyzer users can remotely export readings to their network share. Once a connection is established, users can manually or automatically export a CSV file to their network share and bypass steps associated with data extraction using NitonConnect.</p>

<p>Users do have the ability to average readings on the Niton Apollo Handheld LIBS Analyzer. Operators can take anywhere from 2 to 99 readings and average the readings to create a new mean reading.</p>

<p>The Niton Apollo Handheld LIBS Analyzer provides results in about 10 sec.</p>

<p>The Niton Apollo Handheld LIBS Analyzer uses an argon cartridge to produce an argon purge that enhances the signal (sensitivity) of the analyzer. The argon purge serves to ensure that the lowest limits of detection (LODs) are obtained. Thermo Scientific Analytical Argon cartridges are sold in boxes of 5 and 25 with 1 cartridge lasting about 200 measurements.</p>

<p>While both handheld LIBS and mobile OES provide quantitative analysis, there are a number of key differences to consider.<br/><br/> Operation - Mobile OES applies electrical energy in the form of a spark generated between an electrode and a sample. Analysis is achieved by exciting atoms in the plasma to create an emission spectrum specific to each element. LIBS on the other hand uses a high energy pulsed laser to ablate a sample. The sample forms a plasma with a plume where various atomic and ionic emission lines can be observed and analyzed.<br/><br/> Portability - Handheld LIBS easily and safely travels with a user for various tasks where mobile OES can be difficult to deploy. The Niton Apollo Handheld LIBS Analyzer is equipped with a pistol-grip design and tapered nose to access hard to reach places. Including the battery, the Niton Apollo analyzer weighs 6.4 lbs (2.9 kg). Conversely, a mobile OES can weigh upwards of 40 lbs (18.15 kg) and is mounted to a cart containing a hose, making the total range of motion extremely limited. When factoring in the argon tank required to accompany mobile OES, users can expect to add up to an additional 50 lbs (22.67 kg). Total mobile OES solutions can weigh upwards of ˜90 lbs (40.82 kg) depending on the size of the argon tank. The argon output on the Niton Apollo analyzer has been significantly miniaturized to further aid portability - it contains an internal regulator accepting one argon cartridge weighing less than 14 oz (396.89 g).<br/><br/> Analysis Time - Analysis time on the Niton Apollo analyzer is about 10 sec compared to about 15 sec on mobile OES.<br/><br/> Instrument Setup - The Niton Apollo analyzer is delivered pre-calibrated from the factory. To maintain the device, users must perform daily setup procedures to help normalize the analyzer. Daily setup takes less than 10 min and includes the following: 1) Wave Check - must receive one pass reading of a provided check sample, and 2) Sensitivity Check - must obtain “pass” readings of all check samples for each mode. Daily setup for mobile OES can take upwards of 20-30 min and consists of several complex steps. </p>

<p>Handheld LIBS and XRF are best thought of as complementary technologies. When used together, users can expect to measure a greater range of elements. For example, LIBS can detect lighter elements, such as carbon (C), that handheld XRF is unable to. Handheld XRF is considered non-destructive, while LIBS is minimally destructive. More user maintenance is required for LIBS such as instrument cleaning, sample preparation, and daily setup, whereas XRF requires little upkeep and is best summarized as “point and shoot”.</p>
