Sample Preparation

Sample pretreatment equipment excels in quality, reliability and affordability. Depending on the application, SCP SCIENCE can provide the proper equipment to satisfy your analytical needs and maximize the precision of your final analytical results.

Ashing Crucibles

Quartz crucibles are used for the dry ashing of several organic materials such as plants and dried fruits prior to analysis on an AAS or ICP-OES/ICP-MS.

Fast Steam Distillation Systems

Systems Ranging from Manual to Fully Automatic

  • Fast steam distillation system 3-5 minutes
  • Automatic shutoff
  • pH titration (optional)

 Applications

  • Kjeldahl, TKN & Ammonia
  • Alcohol in wine & beer
  • Phenol & Fluoride

Jaw/Roll Crushers

A sturdier machine with a more powerful motor than previous models, the Jaw Crusher SP-5000 is manufactured for customers with heavy workloads. Grinde crushes 5″x7″ (13 cm x 18 cm) samples to -10 mesh in one pass (93%-95%). Complete with one set of smooth or serrated jaws. Improvements included: more powerful motor (5 HP), moving jaw bearings which are 5 to 10 times stronger; moving jaw shaft 1/2″ diameter longer offering twice the load capacity; and pusher and flange bearings which have twice the capacity. 

• Intergrated forced blown air system to reduce bearing 
  temperatures

• Provides a longer life span for system parts

• Applications include:
    – Rocks, core samples, cements, ingots, glass and friable materials

Soft Material Grinder

The SP-3000 Soft Material Grinder is the ideal instrument to reduce medium to soft material such as grass, pellets, compressed fibers, straw, peat, husks, feedstuffs, spices, hay, hops, wood, tobacco, malt, maize, paper, pastes, roots, rubber, soft soil samples, chemicals, etc.

Material is fed through the top left hopper. A safety plunger allows the operator to vary the rate at which material is fed into the grinding chamber permitting control over the fineness of the final sample. A set of rotating knives cut and shear the sample against a set of stationary knives in the grinding chamber into the sample receptacle.

The SP-3000 Soft Material Grinder is supplied with a metal plate perforated with 1/16″ (approx. 10 mesh) holes. The metal plate can be used as supplied or in conjunction with finer optional screens.

• Three adjustable, sharpenable knives

• Easily-removable screens

• Heavy-duty construction

• Maintenance-free design

• Easily-removable sealed sample receptacle

Swing Mill Grinders

The SCP SCIENCE SP-2000 Swing Mill Grinder provides fast, efficient, reproducible grinding of wet or dry production samples, minerals, ore, rock, cement, brick, slag, coke, and similar materials. Flexibility in sample volume and type are provided by choosing the appropriate grinding dish for your application. The addition of a triple-head Adapter Plate allows three separate 20 or 50 ml grinding dishes to be used simultaneously.

• Digital timer for automatic grinding cycle control

• Capable of sample fineness of -100 to -400 mesh

• Self-adjusting clamp system

• Electrical requirements: 3 Phase, 1 HP motor standard

• (1 Phase motor also available)

Automatic Press

The Auto and Power Hydraulic Presses are power assisted hydraulic systems that apply up to 25 tons of pressure. Designed for a wide variety of pressing applications including XRF and IR sample preparation. 

  • Microprocessor controlled pressure application and release
  • Multi-sequence programming
  • Large working distance between pressing surfaces
  • Low noise operation

Dies & Pellets

Each die is supplied with two stainless steel pellets and a knock-out ring for easy sample extraction. For hard, corrosive, or irregular shaped samples which need pressing, tungsten carbide pellets are recommended and are available for each die size. SCP SCIENCE recommends using AluCAPs as a backing medium. Replacement stainless steel and tungsten carbide pellets are also available separately and sold in sets of two.

Complete line of XRF Pellet Dies

  • Available in 31 mm, 35 mm, 40 mm diameter sizes

 Manufactured from 316 stainless steel grade

  • Provide quality and reliability for years

Designed to accept AluCAPs pellet reinforcing cups

Sample Splitter

Constructed in stainless or galvanized steel, the sample splitter has a wide application since it can be used for fine aggregates as well as many coarse sizes. Sample is poured into the hopper chute and the riffle splitter divides it into two equal portions that discharge into separate pans. The split is then repoured until the desired number of representative samples are obtained. The sample splitters are available with riffle openings of 3/8” or larger, and with splitter sizes of 229 mm x 305 mm (9” x 12”) and 229 x 457 mm (9” x 18”).

Manual Press

The Model C (12 ton) and Model M (25 ton) are ideal for use with XRF pellet dies. Model C is ideal for smaller diameter pellets of more easily compressed material. Model M is suited for larger pellets and harder to press material.

Complete line of manual presses

  • 30, 40 and 50 ton manual presses are available

Offer calibrated gauges in pounds and metric tons

Ensures easy-to-read values

  • Manufactured in cast iron and steel
  • Ensure precision and years of trouble-free use
Binder & Blending Agents The appropriate binder or blending agent will keep the pressed pellet from flaking or disintegrating. Though no single agent may resolve all types of samples, three popular types are available. Ideal application for:
  • Cement, Ores, Fertilizers, Soil, Rock and Alumina
Quantity for X-Ray Mix, Spectro Blend, and Boric Acid in g/lbs: 454/1.

Solid Phase Extraction (SPE) Supplies

PE (Solid Phase Extraction) is a technique whereby a desired analyte, a cation or an anion, is concentrated and separated from a complex sample matrix onto a sorbent stationary phase. The interfering matrix, which is not retained, is effectively eliminated. As a result, the analyte can be analyzed at the best possible sensitivity range of the analytical technique, e.g. Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), without the risk of matrix interference.

In recent years another technique has become very popular, the technique of Matrix Component Retention. In this case, the sorbent is selected to retain unwanted components in the matrix and the analytes of interest are not retained. Again, because the potentially interfering components have been removed, better sensitivity is obtained in sample analysis. This technique is seen most often in the food industry.

In both cases, the sorbent is placed in cartridges or liquid chromatography columns that can hold varying quantities of unprocessed samples.

In general, the SPE method should follow 4 steps:

Step One: Conditioning – The sorbent is prepared for the sample.
Step Two: Retention – Filter the desired analyte(s) or the unwanted matrix components.
Step Three: Rinsing – Any possible undesired component that may have been absorbed on the sorbent is washed away.
Step Four: Elution – The selective desorption and collection of the analyte of interest from the cartridge or column.
