The FAST Flame 2 accessory is a combination of high-speed autosampler, two precision peristaltic pumps and a switching valve, providing quick sample turnaround with fast rinse-out, short signal stabilization times and no sample-to-sample memory effect. The FAST Flame 2 accessory rapidly fills a sample loop via vacuum and then switches to inject the sample loop while the autosampler moves to the next sample, removing the wait time associated with self-aspiration or peristaltic pumping and the long rinse-in and rinse-out times associated with autosampler movement and flushing resulting in sample-to-sample times as short as 15 seconds. Rapid injection and rinse-out result in a throughput of over 560 samples per hour—up to 40% higher than manual analysis for single-element determinations by Flame AA.
FAST Flame 2 provides the ability to mechanically pump the sample during injection, allows for ideal optimization of nebulizer and flame conditions, eliminates variability due to changes in sample viscosity, dissolved solids and tubing length and also provides long-term sample flow stability. Plus, FAST Flame 2 also provides in-line dilution, allowing the analyst to create a single intermediate standard and then the FAST Flame 2 accessory to automatically generate all calibration standards in-line, as required. In addition, FAST Flame 2 can be set to identify over-range samples and then utilize the in-line dilution capability to automatically re-run a sample that falls outside the calibration range at an increased dilution factor to bring the signal within the calibration and provide accurate measurement along with a passed QC check.
Accuracy of dilution is demonstrated by excellent linearity of the calibration curve (R2 > 0.9999). Sample dilution can be predefined on a per-sample basis, allowing for a wide range of dilution factors (1x-50x) to be used when sample types or elemental concentrations vary greatly. The total flow rate delivered by the two peristaltic pumps is constant, but the ratio of the two flows is automatically varied to dilute samples or to build a calibration curve by dilution of a single standard solution.

One of the major challenges in the mining industry occurs early on the in the exploration phase, when determining where to dig. To establish if an area as viable, drilling and sample collection ensues at high volumes, necessitating rapid, accurate and repeatable analyses for minerals and metals of interest.
Automated sample handling solutions such as the FAST Flame 2 sample automation system paired with an Atomic Absorption Spectrometer is discussed here, as crucial components for a high throughput mining setting.
Consumers select fruit juice because it is a tasty, convenient beverage and generally understood to be a more nutritious alternative to carbonated beverages. For 100% juice products, the nutrition content of the original fruit itself is well known, which translates to the expected nutritional value of the final juice product. Detailed labeling is required on food products; for consumers, any comparative variance can be a strong incentive to choose one product over another. In an effort to appeal to consumers and address market needs, many juice products may also be fortified with micronutrients to boost or add to what is already present naturally.
While ICP-OES is generally favored as a multi-element analytical method, the cost savings, simplicity and speed of operation of flame atomic absorption (AA) provides an attractive alternative. This work demonstrates the ability of the PinAAcle™ 900 AA with a FAST Flame sample automation accessory to rapidly and accurately measure nutritional elements in fruit juices.
Milk is an important source of nutrients, mainly for children. Because of its importance, milk is available in several different forms, most commonly as fresh, but it is also available in nonperishable forms (such as powdered and evaporated). Therefore, the requirement exists to analyze several forms of milk for nutritional elements. While ICP-OES is generally favored in a multi-element analytical environment, the cost savings, simplicity and speed of operation of a flame atomic absorption (AA) system provide an attractive alternative. Measuring multiple elements by flame AA requires each sample to be analyzed individually for each element, which impacts the speed advantage of flame AA – however, to address the speed issue, a fast, high-throughput sample automation system can be used.
This work demonstrates the ability of the PinAAcle™ 900 AA spectrometer to reliably and effectively analyze common nutritional elements in a variety of milks over a wide range of concentrations. Coupling the PinAAcle 900 with the FAST Flame 2 sample automation accessory minimizes user error when performing dilutions and making calibration standards increases throughput and provides excellent long-term stability, increasing productivity for the laboratory.
Breakfast is an important meal in providing essential nutrients to keep your energy levels up throughout the day. How do we ensure the food and beverages we consume are healthy, nutritious and safe? Following is a collection of application notes highlighting solutions that will help you identify micronutrients in milk, cereal, juice and fresh and dried fruits as well as toxic metals in tea, dairy products and apple juice to ensure safety of your breakfast foods.
Fortified breakfast cereals are an important source of nutrition for children, and consumers have come to expect high quality from a variety of cereals and continue to select fortified products over non-fortified products in the marketplace. The efficient production of these nutritionally fortified breakfast cereals requires careful formulation and uniformity batch to batch. Ongoing analytical measurement of nutritional additives and the total micronutrient content in the cereal is one way in which food producers can quantify the quality and consistency of their cereal products.
While ICP-OES is generally favored as a multi-element analytical method, the cost savings, simplicity and speed of operation of flame atomic absorption (AA) provides an attractive alternative. This work demonstrates the ability of the PinAAcle™ 900 AA with a FAST Flame sample automation accessory to rapidly and accurately measure nutritional elements in a variety of fortified breakfast cereals.
With an increased focus on healthy living and the consumption of healthy foods, interest in the nutritional quality of the fruit we consume has become more important. When fresh fruit is not available, dried fruit is often substituted, and manufacturers and customers would like to know that the dried fruit has not lost some nutritional value during processing. One way of monitoring the quality of fresh or dried fruit is by measuring the micronutrient concentration contained within. Micronutrients are represented by trace elements considered to be nutritionally valuable, and it is these elements that can be analyzed via various inorganic analytical methods.
While ICP-OES is generally favored as a multi-element analytical method, the cost savings, simplicity and speed of operation of flame atomic absorption (AA) provides an attractive alternative. This work demonstrates the ability of the PinAAcle™ 900 AA spectrometer coupled to a FAST Flame sample automation accessory to analyze common nutritional elements in a variety of fresh and dried fruit.
