Device Description
The FC 500 Flow Cytometer has two cleared configurations:
- MPL (Multi Plate Loader)
- This configuration manages sample preparations using 24 and 96 well plates as O well as 12 x 72mm tubes.
- The workstation contains MXP software for data acquisition, data O managements, instrument management, sample management and sample processing.
- MCL (Multi Carousel Loader)
- This configuration manages sample preparations using 12 x 72mm tubes in a 32 o tube carousel.
- The workstation contains the CXP software and receives data from the O Cytometer to display numeric results and dataplots. The CXP software also includes patient management, control management and LIS components.
Both devices use flow cytometric principles to determine qualitative and quantitative measurements of biological and physical properties of cells and other particles. These properties are measured when the cells pass through one or two laser beams in single file. The instrument can simultaneously measure forward scatter, and five fluorescent dyes using one or two lasers at 488 nm and either 635 nm (solid-state laser) or 633 nm (HeNe laser). Therefore, the instrument can perform correlated multi-parameter analyses of individual cells.
To ensure that the cells move through the laser beam one at a time, the instrument uses hydrodynamic focusing in the flow cell. As the stream of sheath fluid is flowing through the flow cell, a stream of sample is injected into the middle of the sheath stream, The sheath stream surrounds, but does not mix with the sample stream, and its pressure focuses the sample stream so that the cells flow through the laser beam single file.
Before the laser beam reaches the sample stream, cross-cylindrical lenses focus the beam keeping it perpendicular to the sample stream flow while making the beam small enough to illuminate only one cell at a time.
As the cells in the sample stream go through the sensing area of the flow cell, the laser beam illuminates them. The cells scatter the laser light and emit fluorescent light from fluorescent dyes attached to them.
- The amount of laser light scattered at narrow angles to the axis of the laser beam is called forward scatter (FS) which is proportional to the size of the cell that scattered the light.
- The amount of laser light scattered at about a 90° angle to the axis of the laser beam is called side scatter (SS) which is proportional to the granularity of the cell that scattered the laser light (e.g., SS can be used to differentiate between lymphocytes, monocytes, and granulocytes).
- The cells also emit fluorescent light (FL) at all angles to the axis of the laser beam. The amount of FL enables the instrument to measure characteristics of the cells emitting the light, depending on the reagents used (e.g., FL can be used to identify molecules such as cell surface antigens).
The scattered laser light and fluorescent light are collected, separated and measured.
- The FS sensor collects the forward scatter. When the light reaches the FS sensor, the sensor generates voltage pulse signals which are proportional to the amount of light the sensor receives. The signals are processed to measure the characteristics of the cells that scattered the light.
- The pickup lens/spatial filter assembly collects SS and FL from the sensing area of the flow cell. Using a series of filters which reflect specific wavelengths of light towards their respective sensors and allow transmission of longer wavelengths of light, the SS and varying FL wavelengths (produced by fluorochromes such as FITC, PE, ECD, PC5, and ACD) are separated, collected, and measured.
The cytometer has seven sensors, each generating a voltage pulse signal as each cell passes through the laser beam. The voltage pulse signal is proportional to the intensity of the light the sensor received. The cytometer electronics amplify, condition, integrate and analyze these pulses.
The results of sample analysis appear on the workstation screen as graphs in which the user defines the parameters on the plot axes. To analyze the data, regions and gates are defined by the user to select the cells of interest, and then statistics are generated.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Title | Study Description and Outcomes |
---|---|
Pre-acquisition | The test method for the pre-acquisition study induced signal loss prior to the analysis of a sample run, and verified that the software detection tool (SDT) detected the failure, aborted the run and alerted the operator of the signal error. |
Post-acquisition | The test method for the post-acquisition study consisted of 2 test cases utilizing the SDT during data acquisition to detect signal loss: 1) a combination of retrospective data imprinted with failure patterns characterized from field data and prospective sample runs processed through a modified instrument which allowed the user to induce random signal loss and 2) use of the SDT on an additional set of files that were deemed difficult to detect with the pre-mitigation data review instructions. These tests verified that the SDT identified data files with signal loss and alerted the user to review the data plots for the run. |
Real World Data | The testing method for the real word data study applied the SDT to customer files sourced from the field and prospective testing performed with field returned boards with verifiable signal failure. Failures were then confirmed by visual review of the time plots. These tests verified that the SDT identified the failures as corroborated by the visual reviews. |
Reader Study | The testing method for the reader study aligned the user instructions in the IFU for visual review of time plots. In this testing method, the multiple readers were blinded to review 10 files where 7 of these files contained signal loss undetectable by the SDT. Readers followed instructions on the assay IFU and addendum to visually assess the test files. This study confirmed that visual review of time plots identifies signal loss. |
The complementary performance studies confirm the process by which samples with signal loss are detected either prior to acquisition or appropriately quarantined by the SDT, postacquisition, for further review by the user. The use of the SDT, in addition to visual review of time plots provides a comprehensive solution. The studies demonstrated the safe and effective use of the SDT.

Design Change Description:
This modification to the FC 500 Flow Cytometers is being implemented as part of corrective actions for a field action initiated by Beckman Coulter (BEC) in January 2018. The field action was issued on the FC 500 to notify customers that BEC received and confirmed reports of failures causing signal loss and/or signal drifting resulting in the absence of data or a shift in the population in the data plots.
As part of the corrective actions, BEC developed a software update that contains additional risk control measures for the device to mitigate the potential failure modes associated with the reported signal loss and/or signal drift.

that the SDT identified the failures as corroborated by the visual reviews. | |
Reader Study | The testing method for the reader study aligned the user instructions in |
the IFU for visual review of time plots. In this testing method, the | |
multiple readers were blinded to review 10 files where 7 of these files | |
contained signal loss undetectable by the SDT. Readers followed | |
instructions on the assay IFU and addendum to visually assess the test | |
files. This study confirmed that visual review of time plots identifies | |
signal loss. |
The complementary performance studies confirm the process by which samples with signal loss are detected either prior to acquisition or appropriately quarantined by the SDT, postacquisition, for further review by the user. The use of the SDT, in addition to visual review of time plots provides a comprehensive solution. The studies demonstrated the safe and effective use of the SDT.
